In this paper, we propose a content adaptive transform (CAT) method for video coding. Firstly, CAT obtains the transform kernels in real-time instead of predefined fixed ones, and therefore it is content based transform. Secondly, the transform kernels is obtained by singular value decomposition (SVD) from a typical decoded block without transmitting them to the decoder. Thirdly, the optimality property...
Fast intra mode decision algorithms in video coding are very useful and necessary for practical real-time encoder implementation. It reduces the computational complexity by eliminating unlikely modes from candidate set. However, most of these algorithms may lead to the noticeable quality degradation, especially for the all intra coding scenario. To overcome the quality loss while maintaining the fast...
Depth-image-based rendering (DIBR) has attracted more and more attention as a method of virtual view rendering in three-dimensional video (3DV) applications. Many efforts have been dedicated to realize high-quality rendering, ranging from pre-process of the reference depth images to post-process of the virtual texture images. A DIBR method based on inverse mapping and depth-aided image inpainting...
