With the development of three dimensional media resources, the corresponding intellectual property protection problem also occurs. In this paper, a blind stereoscopic image watermarking algorithm based on the relationship modulation is proposed. Firstly, the original stereoscopic images are divided into non-overlapping blocks respectively, and the polarity of these blocks in left and right images...
Wyner-Ziv video coding (WZC) exhibits many properties like low-complexity encoding or embedded error resilience. The quality of side information takes an important role in the performance of WZC. In order to improve the performance of WZC, a new side information interpolation algorithm is proposed in this paper. In our approach, adjacent frames are recombined before encoding. At the decoder, side...
Block-based discrete cosine transform (BDCT) is an important tool in the image and video compression. Blocking artifacts caused by BDCT may be noticeable in the decoded image under low bit-rate conditions. Measuring blocking artifacts is of great significance in the evaluation of image and video image. To ensure reliability of the model outputs, a new no-reference blocking artifacts metric is proposed...
A fast macroblock mode selection algorithm based on inter-view global disparity is proposed to improve the encoder efficiency of JMVM, with insignificant degradation in picture quality and bit rate increase. The proposed fast mode selection algorithm promotes the encoding speed through partly searching method when encoding most of the frames in multiview video sequence. The macroblock mode of current...
