摘要
本文讨论了积分小波变换的快速算法 ,通过尺度函数与小波间的二尺度关系 。
A method based on two scale relations to compute the discrete integral wavelet transform (IWT) is given. The idea is to construct filters for each “voice” directly, and can be accurate as required. By this method, the computational complexity would have nothing to do with the wavelet scaling factor. The method to construct filters for each “voice” is discussed in detail. Finally, and example and the filters are presented.
