A simple FPGA-based conjugate search motion estimator

Conjugate search is an efficient motion estimation algorithm based on block matching for video compression. This paper presents our ongoing work to develop the prototype of the conjugate search motion estimation hardware. So far, we have implemented a simplified version of the conjugate search motion estimation algorithm using field programmable gate arrays. Simulation results indicate that the performance of this hardware is comparable to the one based on full-search algorithm, while hardware is much simpler.
