 Description: The coefficients of the DCT domain motion compensation error or the original image information convert into blocks are represented by different frequency components. It has two advantages: first, signal 1, most of the energy in the small range is concentrated in the frequency domain. Such a description is an important part of several key points. Second, mapping the frequency domain decomposition process to the human visual system.
