Abstract
A motion compensation coding apparatus using a wavelet transformation and a method thereof are capable of detecting a motion vector with respect to a block having a certain change or a motion in an image from a region having a hierarchical structure based on each frequency band and each sub-frequency band generated by wavelet-transforming an inputted motion picture and effectively coding a motion using the detected motion vector. The motion compensation coding apparatus can include a wavelet transformation unit receiving a video signal and wavelet transforming by regions of different frequency bands based on a hierarchical structure, and a motion compensation unit receiving the wavelet-transformed images and compensating the regions having a certain change or motion in the image.
