Abstract
A bottom-up approach to predict wavelets with implicit optical flow is introduced. The presented method is composed of the recursive application of a pel-recursive approach and a wavelet transform. It is compared with a top-down approach theoretically and the existing block motion approach (BMA) with experiments. The presented method shows better performance than BMA for the real image sequence with small motion. It also results in smaller prediction error for the image sequence even with large motion with a prior motion information such as the optical flow of the previous frame or the prediction frame of BMA.
