JCT-3V (Joint Collaborated Team on 3D Video Coding Extension Development) put forward the 3D-HEVC codec scheme for 3D video which is represented by Multi-view Video plus Depth (MVD) format. The format allows a small number of captured views and associated depth maps to be transmitted and other intermediate views will be rendered after decoding by DIBR (Depth Image Based Rendering) techniques. The...
Aiming to the issue of face recognition with partial contiguous occlusion, a new face recognition method was proposed by removing the outlier area in this paper. A mean face image is firstly obtained from train images, which is subtracted by the test face to form an error face image. Then the error face image is used to obtain the occlusion area of the test image by image segmentation technique, and...
In order to improve the processing speed of highly complex video coding that involves high data rate and large amount of computation, a parallel video coding system optimization (PVCSO) method is proposed in this paper. By using PC cluster and general H.264 video coding standard for parallel coding experiments, the important factors that are critical to parallel coding efficiency are thoroughly examined...
In this paper, we investigate the parallel video coding efficiency on PC cluster. Some important factors that affect the parallel coding efficiency are analyzed: network performance, coding algorithm complexity and parallel mechanism. On Gigabit Ethernet PC cluster, a common MPI-based H.264 parallel video coding mechanism was designed, and a large number of tests and in-depth analysis were performed...
