WebDescription. T = graythresh (I) computes a global threshold T from grayscale image I, using Otsu's method [1] . Otsu's method chooses a threshold that minimizes the intraclass variance of the thresholded black and white pixels. The global threshold T can be used with imbinarize to convert a grayscale image to a binary image. WebEdge-based segmentation is a popular image processing technique that identifies the edges of various objects in a given image.
