说明：  基于边缘检测的小波阈值图像去噪在小波阚值去噪的基础上，提出了基于边缘检测的小波阈值图像去噪算法，把高频中的边缘细节与噪声更好地分离开，在主观和客观上去噪效果都比单纯的阈值去噪有所改进。
(Edge Detection Based on Wavelet threshold denoising wavelet Kan denoising based on edge detection is proposed based on wavelet threshold denoising algorithm, the high-frequency noise in the edge detail and better separated, the subjective and objectively de-noising effect than the simple thresholding improved.)
