Inspired by Witsenhausen and Wyner’s 1980 (nowexpired) patent oninterframe coder for video signals,” thispaper presents a Witsenhausen–Wyner video codec, where themotion-compensated previously decod...
The structural similarity (SSIM) index has been found to bea good indicator of perceived image quality. In this paper,we propose a rate-SSIM optimization scheme for mode selection in H.264/AVC video c...
In low bit rate video coding, the frame rate of input sequence can be reduced to the half or even smaller portion by skipping or deleting frames before compression, and then the temporal resolution is...
We propose a perceptual video coding framework based on anSSIM-inspired divisive normalization scheme as an attemptto transform the DCT domain frame prediction residuals toa perceptually uniform space...
This paper presents a novel rate control technique formultiview video plus depth (MVD) based 3D video coding. In theproposed rate control technique, an image-stitching method is firstutilized to...
For most DCT domain distributed video coding systems, xed uniform quan-tizers are used to quantize all Wyner-Ziv (WZ) frames. However, it leads to uctuantvideo quality because the WZ frame quality is...
Stereoscopic video is an important manner for 3-D video applications, and robust stereoscopic video transmission has posed a technical challenge for stereoscopic video coding. In this paper, an auto-r...
Super resolution technique was first proposed for enhancing the image resolution, and then it was expanded to video sequence for obtaining a higher resolution video from low resolution input. Recently...
The coding efficiency of distributed video coding system is significantly determined by the side information quality and correlation model. Motivated by theoretical analysis of the maximum likelihood ...
This letter proposes a distributed video coding (DVC)scheme based on the human visual system (HVS). As we know,HVS can seldom sense any changes below the just-noticeable-difference (JND) distortion th...
Joint video/depth rate allocation is an important optimization problem in 3D video coding. To address this problem, this paper proposes a distortion model to evaluate the synthesized view without acce...
Recently, multi-view distributed video coding (MDVC) receives more and more attention, as its lowcomplexity encoder and high-complexity decoder coding paradigm suits for many applications such as sens...
This paper proposes an image partition based approach to enhance side information quality in low delay distributed video coding (DVC). The proposed method employs a checkerboard pattern to group block...
This paper proposed a novel Region of Interest (ROI) based rate control algorithm for video communication systems, in which the subjective quality of ROI can be adjusted according to users’ requiremen...
Motivated by theoretical analysis of the curve fitting problem based on equivalent kernel, in this paper we propose a local adaptive learning and fusion model for side information interpolation in dis...
