Description
Summary:This work examines the benefits for displaying video content on a 2D screen that can be gained by incorporating depth information into the encoding process. The creation of a 3D model helps to compensate for redundant encoding of reappearing contents beyond group of picture borders, like needed in hybrid video codecs. Starting with filtering the image data, creating a 3D model and applying a model-based compression via MPEG-IV / Part 25 to the model, finally a 2D video representation is rendered. Subjective quality assessments of first preliminary results show, that the perceived video quality is comparable with H.264/AVC encoded videos for low quality scenarios when working with a static 3D model.
