WebAug 2, 2024 · In thresholding operations, you convert grayscale images to binary (black and white) images based on the threshold value. The pixels with intensity values greater … WebIn computer vision and image processing, Otsu's method, named after Nobuyuki Otsu (大津展之, Ōtsu Nobuyuki), is used to perform automatic image thresholding. In the simplest form, the algorithm returns a single intensity threshold that separate pixels into two classes, foreground and background. This threshold is determined by minimizing intra-class …
