利用核逼近思想实现图像的降噪和图像增强，甚至可以利用它来实现分割-Thinking of use of nuclear approximation image noise reduction and image enhancement, and even can use it to achieve the segmentation

这是一个小波降噪的Demo，这个Demo在降噪的基础上还对降噪后的图像进行了补偿复原，使降噪效果大大增强。大家在做类似项目的时候可以参考一下。-This is a wavelet noise reduction Demo, the Demo on the basis of the noise after noise reduction is also compensated image recovery, so that noise reduction effect of greatly enh
