Hash-Based Motion Modeling in Wyner-Ziv Video Coding
Generally, Distributed video coding (DVC) schemes perform motion estimation at the decoder side, without the current frame being available. In order to generate the side-informati...

Frequency Weighting and Selective Enhancement for MPEG-4 Scalable Video Coding
In MPEG-4 scalable video coding, only a small portion of input data is coded in the base layer, and most signal components remain in enhancement layers. In this paper, we propose a...

A 3D Predict Hexagon Search Algorithm for Fast Block Motion Estimation on H.264 Video Coding
In the upcoming video coding standard, MPEG-4 AVC/JVT/H.264, motion estimation is allowed to use multiple references and multiple block sizes to improve the rate-distortion perfor...
