Imagej otsu thresholding

WebImageJ是一款非常优秀的、跨平台的开源软件，里面的源码是用Java编写，之所以用Java是因为Java可以跨平台。 常用的图像处理是基于C++和OpenCV的，所以本人对ImageJ的自动二值化算法进行修改，使其能在C++上也能运行。 ImageJ的自动二值化算法大约有16种，之前有前辈修改之后在C#上运行。 读者也可以去下载本博客的完整测试代 … Web26 apr. 2024 · Image from Wikipedia Otsu thresholding visualization. Algorithmically, first establish the histogram H (see the above illustration, colored in blue).Second, for each threshold t in [0, 255], pixels can be separated into two classes, C1 and C2; those pixels whose Pi < t are put into C1, otherwise into C2.Then, we know the possibilities of C1 and …
