Performance evaluation of motion estimation algorithms for digital signal processors

Current implementations of MPEG2 encoders are specially designed in order to perform a huge number of operations, most of which occur during motion estimation. Many fast algorithms have been proposed to reduce the processing power necessary. This paper examines the results achieved by several methods that show promise for reducing computation while sacrificing as little image quality as possible. Methods that achieve these goals are desirable for use in future encoders that will be implemented on generic digital signal processors (DSPs).
