Studying Temporal Correlation Noise Modeling for Pixel Based Wyner-Ziv Video Coding
Wyner-Ziv (WZ) video coding ? a particular case of distributed video coding (DVC) ? is a new video coding paradigm based on two major Information Theory results: the Slepian-Wolf ...

A reduced-reference structural similarity approximation for videos corrupted by channel errors
Abstract In this paper we propose a reduced-reference quality assessment algorithm which computes an approximation of the Structural SIMilarity (SSIM) metrics exploiting coding too...

Laplacian Distortion Model (LDM) for Rate Control in Video Coding
Abstract. In many rate control models, a uniform weighted distortion has been assumed; that is, the DCT coefficients of the motioncompensation difference frames (residues) conform...

Dither-based secure image hashing using distributed coding
We propose an image hashing algorithm that is based on distributed compression principles. The algorithm assumes the availability of a robust feature vector extracted from the ima...
