HDR and Image Manipulation

Summary: We propose to automatically infer omnidirectional, high dynamic range illumination from a single, limited field-of-view, low dynamic range photograph of an indoor scene. We train a deep neural network that significantly outperforms previous methods. The resulting environment maps are directly used for rendering photo-realistic objects into images.

Summary: We propose the first deep-learning-based approach for inferring a high dynamic range (HDR) image from a single low dynamic range (LDR) input.

Summary: We propose a deep learning HDR reconstruction method, that enables reconstruction of saturated image regions in single-exposure LDR images using a hybrid dynamic range autoencoder. The method can predict visually convincing high resolution HDR images in a wide range of situations, and from a wide range of cameras.

Summary: Image-based edits are commonly applied to multi-channel renderings of 3D scenes. Unfortunately, such edits cannot be easily reused for global variations of the original scene. We propose a method to automatically transfer such user edits across variations of object geometry, illumination, and viewpoint.

Summary: A method to create vector cliparts from photographs. The method decomposes a bitmap photograph into a stack of layers, each layer containing a vector path filled with a linear color gradient. The resulting decomposition is easy to edit and reproduces the clean and simplified look of cliparts.
