中值滤波 阈值变化 边缘检测 图像细化 二值化变化 梯度锐化-Changes in the value of the filter edge detection threshold binary image thinning gradient sharpening

小波去噪程序原码。包括小波分解、、重建、阈值门限设置等可直接使用。 -Wavelet denoising program source code. Including wavelet decomposition and reconstruction, the threshold value threshold set can be used directly.

对噪声图片进行小波变换，采用合适的阈值进行滤波，再对处理后的图像进行锐化处理，得其信噪比-Image noise wavelet transform, using a suitable threshold value filtering processing is then performed on the image sharpening process, obtaining the signal to noise ratio
