Fractal and Multifractal Analyses of Compressed Video Sequences

Irini Reljin and Branimir Reljin

Abstract: The paper considers compressed video streams from the fractal and multifractal (MF) points of view. Video traces in H.263 and MPEG-4 formats, generated at the Technical University Berlin and publicly available, were investigated. It was shown that all compressed videos exhibit fractal (long-range dependency) nature and that higher compression ratios provoke more variability of the encoded video stream. This conclusion is approved from the MF spectra of frame size video traces. By analyzing individual frames and their MF spectra the additive nature is approved.

Keywords: Signal processing, fractal behaviour, multifractal spectrum, standard H.236, MPEG-4.
