Paper Abstract

Efficient video compression is based on three principles: reduction of the temporal, spatial and statistical redundancy present in the video signal. Most video compression algorithm, (MPEGs, H.26x, ...) use the same principle to reduce the spatial redundancy, i.e. an 8x8 DCT transform. However there exist other transforms capable of similar results. Those are the integer 4x4 DCT and the wavelet transforms for instance. This article compare many transforms in the same global compression scheme, i.e the same motion estimation, compensation strategy and the same entropy coding. Moreover the tests are conducted on sequences of different nature, such as sport, video surveillance and movies. This allows a global performance comparison of those transforms in many different scenarios.
