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.

张正友的Easycalib的程序没有提供源代码，这是matlab实现代码，大家试试！(Easycalib Friends of the procedures did not provide the source code, which is to achieve Matlab code, we try!)

说明：  调频信号的时-频分析 针对时变信号有很好的效果(When FM signals- frequency analysis for time-varying signal has good results)

这个是图像轮廓提取的matlab程序，而且提取完后还能把所有轮廓用不同颜色分开存放到轮廓矩阵cell中，方便用户对感兴趣的轮廓进行操作--张璐奉献(This is the matlab image contour extraction process, but also exhausted all the contours extracted with different colors kept separate from the profile cell in the matrix, user-friendly to operate the contours of interest- Zhang Lu dedication)
