Otsu’s Thresholding Method • Based on a very simple idea: Find the threshold that minimizes the weighted within-class variance. WitrynaThresholding. Thresholding is used to create a binary image from a grayscale image [1] . It is the simplest way to segment objects from a background. Thresholding algorithms implemented in scikit-image can be separated in two categories: Histogram-based. The histogram of the pixels’ intensity is used and certain assumptions are …
