1 论文简介
《A new method for gray-level picture thresholding using the entropy of the histogram》是由 Kapur 于 1985 年发表在 COMPUIER VISION, GRAPHICS AND IMAGE PROCESSING 上的论文。该论文首次提出利用最大熵原理计算图像分割阈值,即选取阈值使得图…
Image Thresholding
Goal
In this tutorial, you will learn simple thresholding, adaptive thresholding and Otsu’s thresholding.You will learn the functions cv.threshold and cv.adaptiveThreshold.在这个教程,你将学习简单阈值,自适应阈值&a…
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 …
