摘要: 該文提出了一種不做乘法的整數(shù)小波變換方法,它可以迅速地完成二維可分離小波變換,比傳統(tǒng)的浮點(diǎn)型小波變換在速度上有了很大的提高,并且便于硬件實(shí)現(xiàn),在圖像壓縮上有廣泛的應(yīng)用前景。

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. -
