Abstract

A real-time fractal video compression scheme producing variable bit rate is presented. We use a modified zero searching bilinear Bath-Fractal Transform and exploit temporal redundancies between video frames by transmitting only the most erroneous blocks and by selecting the domain blocks from a special reference frame. A quadtree based segmentation scheme separates moving foreground from quasi static background regions. The scheme is capable of compressing 176 by 144 luminance sequences at 25 Hz on a standard PC with a decompression time of approximately 4 ms per frame. We report compression ratios up to 170:1 at an average PSNR of approx. 29.5 db at 30 Kbits(s. The very fast compression and decompression time makes this algorithm an interesting candidate for interactive video conferencing scenarios. We describe the algorithm, present some sample images and analyze different simulation runs.
