利用小波模极大值计算 可以人工设定阈值 用于检测图像边缘

matlab中小波变换的模极大值重建信号源程序。通过检测小波系数的模极大值，进而实现重建信号源。-matlab wavelet transform modulus maxima reconstruction signal source. By mold detection wavelet coefficients maxima, thus achieving the reconstructed signal source.

包括小波变换去噪和边缘检测两个方面的代码，其中小波去噪代码中包含硬阈值，软阈值和半软阈值三种方法，而小波模极大值方法中包含含噪声和无噪声两种图像的边缘检测-Including the de-noising and edge detection wavelet transform two aspects of the code, where the wavelet de-noising code contains hard threshold, soft and semi-soft thresho
