摘要

Although the advancements in hardware solutions are growing exponentially along with the communicationchannels capacity, high quality video encoders for real-time applications are still considered an open area ofresearch. The majority of researchers interested in video encoders target their investigations towards motionestimation and block matching algorithms. Many algorithms that aim to reduce the total number of requiredmathematical operations when compared to Full Search have been proposed. However, the results oftenconverge to local minima and a significant amount of computations is still required. Therefore, in this research,a hierarchy-based block matching method that facilitates the transmission of high bit-rate videos over standardcommunication methods is proposed. The proposed algorithm is based on the frequency domain, where thealgorithm examines the similarities between a chosen frequency subset, which significantly reduces the totalnumber of comparisons and the total mathematical computations required per block.
