摘　　要：该文提出了一种不做乘法的整数小波变换方法,它可以迅速地完成二维可分离小波变换,比传统的浮点型小波变换在速度上有了很大的提高,并且便于硬件实现,在图像压缩上有广泛的应用前景。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.
