Liquid Wetting across Porous Anisotropic Textiles (Topic: Animation)

Summary: This paper presents a new simulation framework for liquid wetting across porous textiles with an-isotropic inner structure. The influence of the textile's properties on the wetting process, such as contact angle, hygroscopicity and porosity, is considered into the liquid wetting process in detail. By liquid-textile coupling, the wetting process is simulated through liquid absorption/desorption by fiber and liquid diffusion in the means of inner fiber, intersected fibers and capillary action. This framework can simulate the liquid wetting across the porous an-isotropic textile by dripping single or multiple drops of water with realistic results.

A Proposal for Wearable Controller Device and Finger Gesture Recognition using Surface Electromyography (Topic: Hardware)

Summary: Hand and finger motion is very complicated and achieved by intertwining forearm part (extrinsic) and finger part (intrinsic) muscles. We created a wearable finger-less glove controller using dry electrodes of sEMG(surface Electromyography) and only intrinsic hand muscles were sensed. Our wearable interface device is easy to wear and light-weighted. In offline analysis, we identified the tapping motion of fingers using the wearable glove. Totally eleven features were extracted, and linear discriminant analysis (LDA) was used as a classifier. The average of the discrimination result of intersubject analysis was 88.61±3.61%. In online analysis, we created a demo that reflects actual movement in the virtual space by Unity. Our demo showed a prediction of finger motions, and realized the motions in the virtual space.

Aerial Image on Retroreflective Particles (Topic: Hardware)

Summary: We present a new method to render aerial images using the retroreflective particles. Transmissive particles coded by reflective films on half-side behave as retroreflective material. In our method, we place the retroreflective particles in the air. Falling retroreflective particles play a role as a diffuser like a fog screen. By passing the incident light through a plurality of retroreflective particles facing various directions in the air, our display enables to have a wide viewing angle. The result showed that when the 60 degree angle was shifted from the position showing the highest luminance, the luminance at that angle was about 54% of the highest luminance. In addition to the wide viewing angle, the particle size enables the images on this display to be sharp. This system has an advantage that the image can be observed without facing the light source.

Improvement of A Finger-Mounted Haptic Device Using Surface Contact (Topic: Hardware)

Summary: Recently, several researches of haptic device have been conducted. Haptic devices provide users with a perception of touching an object, such as CG by a force feedback. Since they provide a force feedback from a single point on an object surface where users touched, users touch an object by point contact. However, they cannot provide a sense such as humans touching an object with a finger pad because humans do not touch an object by point contact but surface contact. We focused on this characteristic and developed a surface contact haptic device. To touch a CG object in surface contact, we use a plane interface. It provides a force feedback by being approximated to tangent plane on a CG object surface where users touched and the sense of grabbing a CG object with finger pads.

Multi-DOF 3D Printing with Visual Surveillance (Topic: Hardware)

Summary: In this poster, we propose a multi-DOF (degree of freedom) 3D printing system with visual surveillance assistance. Different from common 3D printers with only three translational axes, our printer is equipped with two additional rotational axes, and a visual surveillance module which helps to enhance the printing precision during the rotation. The input model is first segmented such that each part can be printed in a direction with less supporting material. We demonstrate that the proposed system could save most of the supporting materials compared to existing works.

Real-time Temporal Quality Compensation Technique for Head Mounted Displays (Topic: Hardware)

Summary: An asynchronous time warp (ATW) is used to reduce a motion-to-photon latency in head mounted displays (HMDs). To implement the ATW, a graphics processing unit (GPU) must allow to perform the time warp during the image rendering. However, typical GPUs do not support the preemption optimized for the ATW. Even though the preemption is performed in the GPUs, visual artifcat like a judder can occur. Therefore, high priced GPUs with high performance optimized for the ATW must be used to enhance the temporal image quality. In this paper, a new field-prgrammable gate array (FPGA) based HMD system is proposed to perform the temporal quality compensation without using ATW. The proposed system can enhance the perceived image quality in the HMD even when using the typical GPUs with low performance. We develop the hardware system on the low priced FPGA handling output images with the 1440x2560 pixel resolution. Experimental results show that the average PSNR of our system is 30.15dB for the temporal image quality and the total execution time of this system is 1.48 ms. Thus, our system can be implmented in real-time with the improved temproal image quality.

A Deep Convolutional Neural Network for Continuous Zoom with Dual Cameras (Topic: Imaging and Video)

Summary: This paper proposes a convolutional neural network for synthesizing continuous zoom from a pair of images captured by two nearby cameras with two fixed focal lengths. The network is composed of two sub-nets. The first one estimates the disparity map between input images so that they can be aligned. The second sub-net takes the aligned image pair for boosting the image resolution for simulating continuous zoom. We have built a prototype camera system and trained a network for the task. Experiments show that the proposed method can fuse the two captured images effectively and enhance the image resolution.

An Application of Halftone Pattern Coding in Augmented Reality (Topic: Imaging and Video)

Summary: This work introduces a technique to compose markers containing information that can be retrieved a posteriori from a photo. They are an appropriate combination of black and white pixels in such way that some group of pixels are related to symbols of the coded message, and the others are used to yield the aesthetic of marker. These markers can be used for many purposes, including augmented reality applications. They can be easily detected in a photo and the encoded information is the basis for parameterizing several types of augmented reality applications.

Estimating the Simulator Sickness in Immersive Virtual Reality with Optical Flow Analysis (Topic: Imaging and Video)

Summary: In this paper, we conduct an user study to understand the relationship between the optical flow and simulator sickness. We record videos from head-mounted display(HMD) while users are moving around in VR, and then we ask them to take a simulator sickness questionnaire(SSQ) after the experience. Finally, we analyze the optical flow and estimate the correlation with SSQ.

Seamless Video Scene Transition Using Hierarchical Graph Cuts (Topic: Imaging and Video)

Summary: A video clip consists of many scenes and shots. An editor manually cuts and pastes those scenes, placing them in order to compose the clip. This process is one of the most common in video editing. For scene transitions, there are many transition effects available in video editing software. Though transition effects emphasize the transition, there are few effects that seamlessly switch scenes and shots. Here we propose a seamless video scene transition method, which, if available to editors, will provide them with the ability to place the scenes without worrying about transitions. Moreover, one good scene can be composed by seamlessly connecting multiple bad takes using the seamless transition. The main factor that makes a scene boundary visible is the discontinuity between adjacent pixels during a scene change. If these boundary pixel values are similar, scene transition will be less noticeable. We define the difference of pixel values at this boundary as the connection cost. Our method parses the pixels at the scene boundary seams that minimize the connection cost using hierarchical graph cuts.

Style-Oriented Representative Paintings Selection (Topic: Imaging and Video)

Summary: In this work, we proposed a novel method to select representative paintings of an artist. Different from traditional clustering problems, we don't try to assign each image a correct label. We focus on finding the most representative ones in all the paintings. We first use K-means to preliminary cluster an artist's paintings. Clustering centres are the original representative images. Then we employ rejection to pick out the unrepresentative and confused samples. Finally, we update the K classes and get the new representative images.

Subtitle Positioning for E-learning Videos Based on Rough Gaze Estimation and Saliency Detection (Topic: Imaging and Video)

Summary: Subtitle is very common shown in a variety categories of videos, especially useful as translated subtitles for native speakers. Traditional subtitle is placed at the bottom of videos in order to prevent from occluding essential video contents. However, traversing between important video contents and subtitle frequently will have a negative impact on focusing watching video itself. Recently, some research work try more flexible subtitle positioning strategy. However, these methods are effective with restrictions on the video content and devices adopted. In this work, we propose a novel subtitle content organization and placement framework based on rough gaze estimation and saliency detection.

Dualboard : Integrated User Interface between Typing and Handwriting (Topic: Interaction)

Summary: Currently, a variety of digital devices and associated input interfaces are being introduced. However, when you need to write down something important quickly and precisely, you may use a traditional input such as a pen. For example, while using digital devices, you may still need to find a notepad and a pen, which can be an inconvenience if you need to store and modify something that you've written down. This concept provides an integrated user interface where it is possible to continuously and naturally switch between typing and handwriting while performing tasks on the computer, one of the most representative digital devices.

Perception Adjustment for Egocentric Moving Distance between Real Space and Virtual Space with See-closed-type HMD (Topic: Interaction)

Summary: This paper presents a study of egocentric distance perception matching between real space and see-closed type HMD based virtual space. We need a calibration technique that reflects these characteristics when implementing virtual interaction directly tied to real-world space. This study experimentally analyzes the phenomenon in which the distance perceived by the user decreases when they are in HMD environment. Then, we provide a correction algorithm that allows users to maintain the distance perception sensed in the real space in the virtual space.

Prototyping Digital Signage Systems with High-Low Tech Interfaces (Topic: Interaction)

Summary: We prototyped interactive digital signage systems with custom-made physical interfaces to investigate how the addition of physical interfaces extends the design space. While our investigation is still in a preliminary phase and the prototypes just simply playback video files, being triggered by the user's action made to the interface, the addition of physical interfaces seems to provide an interesting design space; the addition can be not just helpful for an intuitive interaction but also beneficial as a mean of creative expressions for better message delivery by digital signage.

User Interface Applications in Desktop VR using a Mirror Metaphor (Topic: Interaction)

Summary: The main objective of this research work is to create a desktop VR environment to allow users to interact naturally with virtual objects positioned both in front and behind a screen. We propose a mirror metaphor that simulates a physical stereoscopic screen with the properties of a mirror. In addition to allowing users to interact with virtual objects positioned in front of a stereoscopic screen using virtual hands, the virtual hands can be transferred inside a virtual mirror and interact with objects behind the screen. When the virtual hands are operating inside the virtual mirror, they become like the reflection in a real mirror. We present application scenarios that would make use of the expanded interactable space in a desktop VR environment created by the proposed mirror metaphor.

An Image Generation System of Delicious Food in a Manga Style (Topic: Methods and Applications)

Summary: In non-photorealistic rendering, preserving material appearance is challenging in terms of human sensitivity. Foods in manga are one of such topics. While the types of images presented in manga can range from realistic to deformed, foods are generally drawn as realistic, delicious-looking images. However, drawing such pictures requires skill. Thus, we propose a system that emphasizes the gloss of wet and oily foods to generate delicious food pictures in a manga style.

DeepHolo: Recognizing 3D Objects using a Binary-weighted Computer-Generated Hologram (Topic: Methods and Applications)

Summary: Three-dimensions (3D) models contain wealth of information about every object in our environment. However, it is difficult to semantically recognize the media forms, even when they feature simply form objects. We propose a DeepHolo network using binary-weighted computer-generated hologram (CGH) from point cloud models. This neural network facilitates manipulation 3D point cloud form, and allows for processing as Three-dimensions (2D) data. We construct the network using hologram data, as binary holograms are more simply and lower information volume than their point cloud data(PCD), leading to more less number of parameters. We then employ a Convolutional Neural Network to extract features by muting distracting factors. The Deep Neural Network (DNN) is trained to recognize hologram of 3D objects, so that it is close to a point attributed to a 3D model of a similar object to the one depicted in the hologram. This purifying capability of the DNN is accomplished with the help of large amount of training data consisting of holograms from PCD. DeepHolo network allows high precision object recognition, as well as processing 3D data using a little of computer resources. We evaluate our method on a recognition task and show that it is much more space efficient outperforms state-of-the-art methods.

Improved and Accessible E-book Reader Application for Visually Impaired People (Topic: Methods and Applications)

Summary: This paper presents a study of an accessible e-book reader application for visually impaired people. We interviewed 27 visually impaired people to understand their usage patterns of e-books and user requirements in terms of functions and interface of an e-book reader application. Based on this survey, we were able to establish the basic direction of development of our e-book reader application; we implemented the first version of the e-book reader focusing on basic functionality. This version of the e-book reader obtained a value of user satisfaction of more than 75% in the usability test. We are continuing to develop the next version of this e-book reader with differentiated functions for reading professional books that include equations, tables, graphs, and so on. In addition, we are considering supporting a simple and fast input method and providing personalized UI. Beyond e-book readers, we hope that our study will be useful when designing and developing various mobile applications, considering that visually impaired users want to obtain information and experience equal to that available to the non-visually disabled.

MitsuDomoe: Ecosystem Simulator of Virtual Creatures in Mixed Reality Petri Dish (Topic: Methods and Applications)

Summary: This project introduce a new tool for science education by using mixed reality. Our objective is to create a new technical platform for augmenting the creative experience of users in science education. We developed a virtual ecosystem simulator with physical mixed reality interface. Users can manipulate the computed ecosystem, and/or test their own simulation models again and again, without losing real lifeforms. Users interact with the ecosystem via the petri dish displays and a pipette-like device. The physical MR interface can provide users with the sense and enjoyment of performing experiments in a laboratory. The ecosystem model consists of three species of primitive artificial creatures and simulates the predation cycle of these virtual species in the petri dish device. The proposed simulation model assumes a symmetric and cyclical relation between three species that have essentially the same functions. In this scheme, the species have a predator-prey relation, but each species can behave as both predator and prey. By tuning the factors of the model, species can be changed to exhibit offensive or defensive behaviors. User can control the factors by dropping virtual chemical liquid from the palette into the petri dishes. In this system, there are two types of user interface for participating in the experience, the physical MR and immersive VR interfaces. With the VR interface, users can also experience immersive observation. Users can join the world from both of inside and outside. They can discuss and share the experience from each viewpoint. We expect this MitsuDomoe system prototype to serve as a new technical platform for augmenting the creative experience of users in science education.

Polyhedral Meshes with Concave Faces (Topic: Modeling)

Summary: We study the design and optimization of polygonal meshes with concave planar faces. The motivating applications of this work are architecture, product design, and art. To discretize freeform surfaces into polyhedral meshes, we propose a novel class of regularizers for mesh aesthetics based on symmetries. They are useful to generate concave polygons on negative Gaussian curvature region and provide the necessary flexibility to create smooth transformation of planar faces across the region where Gaussian curvature alternated between positive and negative.

A Fast And Efficient Content Aware Downscaling Based Texture Compression Method For Mobile Devices (Topic: Multimedia)

Summary: Texture compression techniques have been of great interest especially for mobile phone industry due to the relatively smaller amount of memory available. Current texture compression encoding techniques are slow and CPU intensive, making it not suitable for on the fly encoding of uncompressed textures to compressed ones. To address this draw-back, we present a fast and effective approach to reduce the run-time memory footprint of images. We apply a compression mechanism which uses image downscaling adaptive to the image content. The compression technique does not cause any perceivable loss of quality. In our experiments we show that proposed method is on an average 6 dB higher in PSNR than Bi-linear uniform image downscaling technique at equal bits per pixel.

Content-Based Measure of Image Set Diversity (Topic: Multimedia)

Summary: A novel method is presented for quantitatively measuring the diversity of image set that represents a rich visual vocabulary. We use deep learning techniques to find correlation and disparity among given photos to facilitate their embedding. We define the diversity of an image set as the extent to which the contents that are presented are different from each other from three aspects, variety, balance, and disparity, based on distance of image visual features which equals to the reciprocal of similarity. In addition, we develop as application that selecting the most diverse subset providing convenience for having a global view of the set.

Eyeshine Rendering: A Real Time Rendering Method for Realistic Animal Eyes (Topic: Rendering)

Summary: In the eyeball of animals, there is a reflective layer called tapetum lucidum underlying the retina, which reflects the light entering the eyeball. The tapetum lucidum is necessary for animals to see objects in the dark. Animals' eyes may look shiny in the dark because the tapetum lucidum reflects the light incident on the eyeballs. As tapetum lucidum reflects light, the black eye of an animal may appear to emit light or it may appear to be a bright color. This visible effect of the tapetum lucidum is called as "eyeshine", causing the pupil to appear to glow when a light is shone into the eye of animals. However, here are many games in which animals appear, however, very few games have reproduced fairly faithfully to eyeshine. In this paper, we propose a real-time rendering method considering tapetum lucidum reflection. We aim to establish a technique to express the eyeshine of animals more realistically.

Importance Sampling Measured BRDFs Based on Second Order Spherical Moment (Topic: Rendering)

Summary: BRDF importance sampling, which generates sampled directions in a pattern that closely matches the BRDF, is a powerful tool for variance reduction in Monte Carlo rendering. Conventionally, it is challenging to design proper sampling patterns for measured BRDFs since no analytical expression is available directly. Although tabulation based sampling strategy provides a feasible solution to this problem, it usually requires a high memory consumption for additionally storing the importance functions. In this poster, we show that the second order spherical moment of a BRDF can be leveraged in deriving a robust sampling function for the BRDF. This sampling function has an analytical form of a GGX distribution which resembles the shape of the raw BRDF measure. Besides efficient computation and compact storage brought by the GGX distribution, another benefit is its possibility to perform sampling according to the distribution of visible normals. This can further reduce the variance especially for diffuse-like materials and improve the convergence rate of the Monte Carlo numerical integration.

Marker-less Real-Time Tracking of Texture-less 3D objects from a Monocular Image (Topic: Virtual Environments)

Summary: We propose a method for estimating 3D posture of a texture-less object for spatial augmented reality (SAR) by using a monocular image. In recent years, SAR using image projection technology has been attracting attention. SAR is expected to become one of the next-generation AR technologies, because the image projection technique realizes a virtual object by overwriting the appearance of a real object and achieves physical interaction with them. For overwriting the real object to realize high reality, real-time posture estimation of the projection target is quite important. Because the use of sensors for the posture estimation greatly affects the appearance of the target object, non-contact measurement using a camera is desirable. However, the projection target for SAR is often texture-less in order to achieve better image projection. In addition, if the target contains texture, it is cancelled by the projection. Therefore, it is not possible to use the image feature quantities that are often used in camera-based approaches. In this study, using the contour information of the projection target, we propose a method that enables the position and the orientation estimation of a texture-less object in real time by using a monocular image.
