摘要
寻找简单实用的图像阈值自动选取方法一直是许多图像处理工作者的工作目标。目前已提出的图像阈值选取方法虽多达数十种 ,但常用的仍然只有Otsu方法、最大熵法、矩量保持法、简单统计法等这几种。受Otsu方法的启示 ,本文提出了一系列与之有类似表达式的简单实用阈值选取方法 ,所有方法均通过一些典型图像验证证明其是行之有效的。
It has long been the ambition of many researchers working in image processing and analysis to find simple and practical threshold selection methods. Although over sixty methods for image threshold selection have been put forward, only few are used usually. Under studying some old methods, such as Otsu′s method, some new methods for image threshold selection are put forward in this paper. They have been tested successfully to be able to work well in many images.
