摘要
依据信号与噪声的小波变换在不同分辨率下呈现不同特性的特点，提出了多分辨率支集图像低通滤波方法。通过与经典的高斯低通滤波方法实验结果比较。
Multiresolution support for lowpass filtering is introduced according to different property of wavelet transform for signal and noisy at different scale. Compared with Guassian filtering method, it possesses more powerful noise immunity.
