Abstract

In this paper, a novel architecture for transformdomain motion estimation is proposed. We derive arecursion equation from the algorithm and wavefrontarray processors are used to perform motion estimationalgorithm adaptively in the transform domain accordingto the compression ratio. It is also shown that a higherthroughput rate with the reduction of arithmetic buildingblocks, frame memory size and the number of memoryaccesses is achieved. The proposed architecture canalso reconfigure to different algorithms that can be usedto perform power-aware video encoding. Simulationresults on video sequences of different characteristicsshow comparable performance of the proposedalgorithm to spatial domain approaches in the aspectsof PSNR and compression ratio.

ICAI'08: Proceedings of the 9th WSEAS International Conference on International Conference on Automation and Information

Motion estimation is one of the most important steps in video compression algorithms. It reduces temporal redundancy present in frame sequences and allows a better compression of video material. Most of the actual video compression algorithms use "block ...
Rate-distortion optimal motion estimation algorithms for motion-compensated transform video coding

Motion estimation and compensation is widely used for exploiting temporal correlation within an image sequence. To find motion vectors that lead to high compression, most motion estimation approaches use a source distortion measure, such as mean-square ...
Analysis of IDCT and motion-compensation mismatches between spatial-domain and transform-domain motion-compensated coders

Many studies have performed transcoding of compressed video streams in the discrete cosine transform (DCT) domain to reduce computational complexity. On the other hand, most video compression standards recommend motion compensation in the spatial ...
