MATLAB Image Binarization & Thresholding

In MATLAB, the imbinarize function can be used to perform binarization processing on an image. this function takes the image and a threshold as input parameters, setting pixel values in the image greater than the threshold to 1 and those less than or equal to the threshold to 0, thus converting the image to a binary image. In addition to the imbinarize function, the graythresh function can also be used to automatically calculate the threshold for binarization. The graythresh function takes the image as an input parameter, automatically calculates the optimal binarization threshold, and returns it to the user.
