Channel-Divided Distributed Video Coding with Weighted-Adaptive Motion-Compensated Interpolation

Adaptive Interpolation Filter for Motion Compensated Hybrid Video Coding

Common hybrid video coding standards such as H.263, MPEG-1,2,4 are based on motion compensated prediction. For the motion compensated prediction purpose, displacement vectors with fractional-pel resolutions (e.g. 1/2-pel or 1/4-pel) are used. In order to estimate and compensate fractional-pel displacements, the image signal has to be interpolated. The most popular and very simple interpolation ...

Motion compensated Prediction in Distributed Video Coding

The ongoing research in Distributed Video Coding (DVC) for low complexity encoding is trying to shorten the substantial performance gap to well known state-of-the-art coders. One of the reasons for this gap is the motion estimation without the reference frame. In this paper we look at what motion estimation to use. Furthermore we compare the two possible methods to get a motion compensated pred...

Switched control grid interpolation for motion compensated video coding

In this paper, fundamental limitations of the Control Grid Interpolation and Block Matching schemes for motion compensation are remedied by a novel idea which embodies positive features of both schemes. The enhanced scheme performs both consistently and signiicantly better than either method does individually.

Motion-compensated Video Coding Techniques

The ever-increasing demands of the modern telemetry system for the transmission of high resolution digital video data at primary and sub-primary bit rates necessitate the employment of efficient motion-compensated video coding algorithms. This paper reviews the current status of motion compensation techniques. The two major classes of motion estimation methods currently being used for predictiv...
