Abstract

We propose a novel video coding scheme requiring a simple encoder and a complex decoder where video frame is intra-coded periodically and the intermediary frames between the successive intra-coded frames are coded efficiently by a proposed irregular binning. We investigate a method of forming an irregular binning which is capable of quantizing any value effectively with only small number of bins. Based on the fact that successive frames in a video are highly correlated, the video reconstructed at the decoder is enhanced gradually by applying POCS (projection on the convex sets). After an image frame is reconstructed with the irregular binning information at the proposed decoder, we can improve the resulting quality more by modifying the reconstructed image with motion-compensated data from the neighboring frames. In the proposed decoder, several iterations of these modification and re-projection can be performed. Experimental results show that the performance of the proposed coding scheme is slightly lower than that of H.264, and thus can be an alternative of H.264 in the applications requiring a simple encoder.
