Otsu method คือ

WebOtsu's thresholding method [1] is useful to automatically perform clustering-based image thresholding. The algorithm assumes that the distribution of image pixel intensities follows a bi-modal histogram, and separates those pixels into two classes (e.g. foreground and background). The optimal threshold value is determined by minimizing the ... WebOtsu method is that it considers only two classes in histogram but most of the time there are more than two classes of pixels in a digital image so in that condition the Otsu …
