摘要
We describe a system for still image compression that uses several transform sets in a multiple bases realization algorithm. Our algorithms reduce the number of encoded transform coefficients 20% beyond DCT-only compression. We extend these algorithms to use several newly developed LOT bases, resulting in useful algorithms for low bit rate (high compression) operation without blocking effect.
