这是利用二维小波变化对图像进行消噪的例程，图像所含噪声主要是白噪声，主要集中在高频部分，程序给予了实现(Routine changes in the two-dimensional wavelet image denoising, image noise is mainly contained in the white noise is mainly concentrated in the high frequency part of the program given to the realization)

Thresholding is used to segment an image by setting all pixels whose intensity values are above a threshold to a foreground value and all the remaining pixels to a background value. Whereas the conventional thresholding operator uses a global threshold for all pixels, adaptive thresholding changes the threshold dynamically over the image. This more sophisticated version of thresholding can accommodate changing lighting conditions in the image, e.g. those occurring as a result of a strong illumination gradient or shadows.
