The feasible implementation of immersive 3D video systems entails the need for a substantial reduction in the amount of image information necessary for representation. Multiview image rendering algorithms based on depth data have radically reduced the number of images required to reconstruct a 3D scene. Nonetheless, the compression of depth maps still poses several challenges due to the particular...
In recent years, there has been a growing interest in developing novel techniques for increasing the coding efficiency of video compression methods. One approach is to use texture and motion models of the content in a scene. Based on these models parts of the video frame are not coded or “skipped” by a classical motion compensated coder. The models are then used at the decoder to reconstruct the missing...
A video coding approach that uses texture analysis at the encoder and synthesis at the decoder is presented. It is characterized by scaling of texture reconstruction accuracy at the decoder according to perceptual relevance to the viewer. A closed-loop concept is proposed for a fully automated approach that can be integrated into any video codec. Besides texture analysis and synthesis, the loop encompasses...
