Abstract

This work proposes and implements a simple and efficient video encoder based on the compression of consecutive frame differences using sparse decomposition through matching pursuits. Despite its minimalist design, the proposed video codec has performance compatible to H.263 video standard and, unlike other encoders based on similar techniques, is capable of encoding videos in real time. Average PSNR and image quality consistency are compared to H.263 using a set of video sequences.
