Research On 3D Video Coding Algorithm

3D video includes stereo video and multi-view video, which can provide viewers with benefits of realism and selective viewing. Researchers in video field become more and more interested in it. With the development of video coding technology,3D video will replace HDTV and become the novel research area in video technology.However, compared to single view video, the data amount of multi-view video increases along with the increase of the view number. So more effective method to encode the video data must be attained in order to make 3D video storage and transition easier. Thus we focus on improving the performance of codec in this paper.Firstly, there will be some talk about conception of 3D video, the application of it and following it, some key technology of H.264 video coding will be introduced.Secondly, multi-view video coding method based on H.264 will be discussed. It uses disparity prediction and motion prediction, so it proves to be a good method for 3D video coding. There will be a discussion about research of MVC. It's coding structure will be analysed.Lastly, some improvements about the existing coding structure are made, the selection of I-view is adjusted and some inter-view prediction is removed. Based on the test result, we can say that the improved structure can improve the random access performance and reduce coding complexity without affecting the performance of MVC too much.
