H.264/AVC is newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. Stereo video technology is an active research area in current video signal processing filed. More and more researchers are engaged in this field. In this paper, stereoscopic video coding is studied, and three schemes of using H.264/AVC are discussed. An improved scheme is...
Two video coding schemes with variable bit rates-JPEG 2000 and H.264/AVC-were compared in terms of perceived quality performance in a Digital Cinema environment. In this paper we describe in detail the procedure for a subjective quality assessment. The stimuli used were 10 seconds long color sequences at HD resolution (1920×1080 progressive), 30 fps, and YCbCr 4:2:0. We do not consider DCI-specified...
Human faces provide a useful cue in indexing video content. In this paper, we propose a novel face detection algorithm based on a convolutional neural network architecture that can rapidly detect human face regions in video sequences encoded by H.264/AVC. By detecting faces directly in the compressed domain, we use the discrete cosine transform (DCT) coefficients in H.264 intra coding as the feature...
