Abstract

Zhang and Zafar (see ibid., vol.2, no.3, p.285-96, 1992) proposed a video compression scheme based on the wavelet representation and multiresolution motion compensation (MRMC). An additional masking module is created to further enhance its efficiency. Specifically, between the modules of wavelet decomposition and MRMC, the masking module is inserted which constructs binary images based on the difference of the wavelet coefficients. The binary images serve as masks to facilitate a more efficient motion compensation. Experiments show that the processing time could be significantly reduced from that required for a full search in the original MRMC algorithm
