The existing disparity map based virtual view rendering may decrease the sharpness of the rendered image, or result in ghosts. In this paper, a new disparity map based virtual view rendering method is proposed. The left and the right view images and their corresponding disparity maps are used to render intermediate virtual view image respectively. Then the two rendered images resulted from the left...
Asymmetric stereoscopic coding can save bitrate and maintain the overall visual quality of stereoscopic perception, so it is an alternative for wireless environment in which the bandwidth is limited. In asymmetric stereoscopic coding, the right-view images are down-sampled to half resolution before coding, while the direction of sampling influences the rate-distortion performance of the asymmetric...
Multiview video coding is one of the key technologies in 3D video applications. However, considerable computational complexity is existed in multiview video encoding. In this paper, we propose a fast macroblock mode selection and disparity estimation algorithm. Firstly, the proposed algorithm terminates early the modes search process according to the correlation of modes in the corresponding locations...
Asymmetric stereoscopic video coding can save the bitrate and maintain the overall visual quality of three dimensional perception. But for mobile three-dimensional television, the original full resolution restoring is complex for the decoder. In this paper, a decoding and up-sampling optimization scheme for asymmetric stereoscopic video coding is proposed, in which macroblocks encoded with SKIP mode...
A fast macroblock mode selection algorithm based on dynamic multi-threshold is proposed to improve the encoding speed of multiview video, but with insignificant degradation in rate distortion (RD) performance. The macroblock modes are divided into four classes after statistically analyzing the macroblock mode selection results. Three thresholds are adopted based on the great RD cost gaps between the...
A novel variable bit rate (VBR) control method is proposed for single-pass audio video coding standard (AVS) video encoding in this paper. An efficient scene change detection method based on peak signal to noise ratio (PSNR) is introduced to solve the problem of quality degradation in subsequent frames when scene changes occur. Furthermore, the proposed rate control method can be efficiently adapted...
Image quality assessment is an important problem image processing. In this paper, an image evaluation algorithm based on fuzzy theory is proposed to predict the quality level of right view image in compressed stereoscopic video. Block-based disparity estimation between stereoscopic videos is used in evaluation processing. With the help of inter-view correlation, the reconstructed left view at decoder...
