Video compression uses Motion Estimation (ME) technique to achieve very high compression ratio.However ME is the most computational part of video encoding.Therefore development of many fast ME algorithms have been done to reduce the computations.Block-based techniques are the most popular one due to its simplicity.This research paper implements five Block Matching Algorithms ( BMAs) namely Exhaustive Search (ES), Three Step Search (TSS), New Three Step Search (NTSS), Four Step Search (4SS) and Diamond Search (DS).Their performances are compared and analyzed based on the number of computations and PSNR.
