摘要：

This letter presents a new perspective to block motion estimation for video compression referred to as high-frequency component matching. Taking into consideration the features of the transform encoder used to encode the prediction error in the motion-compensated predictive coding system, motion estimation is carried out such as to compensate for high-frequency components, leaving the compensation task of low-frequency components to the transform encoder. It is shown that this approach can outperform standard motion estimation that does not take transform encoder features into account and has the potential of changing the way motion estimation is being performed in video compression standards.
