Abstract In this paper,an algorithm of wavelet transform without multiplication is introduced. It can implement 2D separable wavelet transform rapidly. The speed of transform is greatly improved comparing to the classical float algorithm. It is also easy to be implemented in hardware. This algorithm will have broad application potentials in image compression.
