Image Processing - Otsu's method 目录 回到顶部 概述 Otsu's method 也叫全局最优阈值处理,使用聚类思想,将图像分为“前景”和“背景”两类,并使得上述两类的类内方差最小,即类间方差最大。 图1 原图像 图2 使用 Otsu's method 进行二值化后的图像 回到顶部 算法 σ2w(t)=ω0(t)σ20(t)+ω1(t...
Otsu's Method Otsu's method In computer vision and image processing, Otsu's method is used to automatically perform histogram shape-based image thresholding,[1] or, the reduction of a graylevel image to a binary image. The algorithm assumes that the image to be thresholded contains two ...
This article presents a new approach in image processing for detecting cracks in images of concrete structures. This method involves three steps: First; change the image to a gray and using edge of the image and use Sobel's method and development of an image filter using Sobel's filter for...

Therefore, a method com-bining three infrared image processing algorithms is introduced to enhance the infrared image in order to solve the problems of low SNR and contrast of infrared images. Based on analyzing the noise sources, ed-dy current infrared images are preprocessed by arithmetic ...
