My research interests are on almost anything related to image and video processing, including 2D to 3D conversion, disparity estimation, view interpolation, high dynamic range, super-resolution, de-noising, film grain management and compression.
3D content conversion
During 2011, our research was focused on new inpainting, aphamatting & compositing algorithms to improve the user-assisted 2D to 3D conversion workflow of Technicolor’s 3D Conversion BU. Our research work was used in production during the 2D to 3D conversion of Dreamwork’s Kung Fu Panda animation film. Since January 2012, our research has shifted to automatic algorithms to convert enriched 2D sources (with satellite views and depth information) to stereoscopic 3D and multi-view 3D. We also continue our research on disparity estimation and view interpolation for correction & repurposing of stereoscopic 3D video. Cross-site team in R&I Hanover, Germany and R&I Rennes, France.
Tiger 2D & 3D encoder for Blu-ray
Participated in the creation of Technicolor’s AVC & MVC encoder for Blu-ray. Encoded the 3D version of Dreamwork’s Monsters vs. Aliens animation film for the first commercial Blu-ray 3D disk.
Film Grain Technology
Co-invented Film Grain Technology: parametric representation of film grain characteristics for improved coding efficiency of film content. FGT was trademarked by Thomson and components of it are part of the H.264|AVC standard, HD DVD-Video specifications and the current CBHD format. Authored the official FGT specifications, published by SMPTE and created reference software and test streams.
