摘要：
Zhang and Zafar proposed a video compression scheme based on the wavelet representation and multiresolution motion compensation (MRMC). In this letter, an additional masking module will be created to further enhance its efficiency. Specifically, between the modules of wavelet decomposition and MRMC, the masking module will be inserted which will construct binary images based on the difference of the wavelet coefficients. The binary images will serve as masks to facilitate a more efficient motion compensation. Experiments show that the processing time could be significantly reduced from what is required for a full search in the original MRMC algorithm.
