It obtains the optimal threshold for image segmentation by the maximum between-class variance, without considering the minimum... In 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 … Visa mer The algorithm exhaustively searches for the threshold that minimizes the intra-class variance, defined as a weighted sum of variances of the two classes: Weights Visa mer • Implementation of Otsu's thresholding method as GIMP-plugin using Script-Fu (a Scheme-based language) • Lecture notes on thresholding – … Visa mer Otsu's method performs well when the histogram has a bimodal distribution with a deep and sharp valley between the two peaks.
