This set of foils describes image and video compression schemes concentrating on Wavelets which seem most powerful although JPEG and MPEG using related but less efficient Fourier technology will be used much more widely initially |
JPEG, JBIG, Fractal for images and MPEG, H.261 schemes for video clips are briefly reviewed |
Wavelets are described in detail |
