Otsu’s Thresholding的工作原理
在双峰图像(像素的直方图只包含两个峰值),一个好的阈值将在这两个值的中间。Otsu算法就是从图像的像素直方图中确定了一个最佳的全局阈值 t t t,可以最小化weighted within-class variance加权类…

Simple Thresholding
The function cv.threshold is used to apply the thresholding. The first argument is the source image, which should be a grayscale image. The second argument is the …
