Abstract :
We propose a new frame rate upconversion algorithm using the wavelet transform. In the proposed scheme, motion estimation is performed using the information in the wavelet-transformed subbands. In addition, an effective compensation method for the occlusion areas, called overcompensation, is presented. Computer simulation shows a higher performance of the proposed upconversion scheme than conventional methods.
