matlab下编写的谱相减函数，用作语音增强(prepared under matlab spectral subtraction function, used for speech enhancement)

Code for denoising images. This code differs from standard wavelet denoising techniques in that it uses non-orthogonal wavelets, and unlike existing techniques, ensures that phase information is preserved in the image. Phase information is of crucial importance to human visual perception. Also, this code does have an effective way of determining threshold levels automatically. (Code for denoising images.

同一张图片的各种不同的显示，以及对图片进行对比，能明显看出其中的不同(different to show the same picture)

图像增强技术属于数字图像预处理的范畴, 直方图均 衡化和规定化处理是图像增强技术中的基本方法。(Image enhancement technology areas are digital image preprocessing, histogram equalization and provides image enhancement processing technology is the basic method.)

说明：  典型的SAR回波模型，对初学者还可以。大家可以下载下来调试一下(A typical SAR echo model, beginners can also)
