otsu算法确定二值化阀值，最大类间方差是由日本学者大津(OTSU)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。 -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 t

大津算法源代码加注释，功能是自动选取图像的最佳阈值，非常适合初学者！-Otsu s method annotated source code, the best feature is the automatic threshold images, very suitable for beginners!

最大类间方差法是由日本学者大津(Nobuyuki Otsu)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2部分。背景和目标之间的类间方差越大,说明构成图像的2部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2部分差别变小。(The largest between-class variance method was proposed by the Japanese scholar Nobuyuki Otsu

自编实现大津算法，最大类间方差图像二值化matlab程序。(The self-compiled matlab program realizes the Otsu algorithm and maximizes the inter-class variance image binarization.)
