| 摘 要： | 为了在滤除图像噪声的同时能很好地保持图像的细节，提出了一种基于自适应边缘检测的小渡包图像去噪方法，先用自适应滤波多尺度边缘检测方法检测出图像的边缘，小波包去噪时就可选用全局闽值而不必担心损害图像的边缘特征。实验结果表明，谊方法不但可以保持图像的边缘信息，而且能够提高去噪后图像的信噪比。

| Abstract: | In order to preserve image details as well as canceling image noise,a wavelet package image de-noising method based on ad-aptive edge detection was presented.Edges of an image were detected with method of adaptive filter sales for edge detection firstly,and then a global threshold was used in wavelet package de-noising without damaging image's edges.Experimental results showed that the algorithm could not only keep edge information of image,but also could improve signal-to-noise ratio of an image. |
