采用OpenCV实现OSTU算法，采用lena图像作为实例，可实现边缘检测-The OpenCV realize OSTU algorithm, using Lena image as a example, may realize the edge detection

代码实现大津法算法(OSTU)，可以实现对灰度图的二值化(黑白图像)-The code to achieve the the Otsu Algorithm (OSTU), can be achieved binarization of grayscale (black-and-white images)

采用ostu算法，再经形态学分析去除小面积提取菠萝果实图像。(Using ostu algorithm, and then by morphological analysis to remove small area extraction pineapple fruit image.)

大津法（OTSU）是一种确定图像二值化分割阈值的算法，由日本学者大津于1979年提出。从大津法的原理上来讲，该方法又称作最大类间方差法，因为按照大津法求得的阈值进行图像二值化分割后，前景与背景图像的类间方差最大（何为类间方差？原理中有介绍）。(Otsu method (OTSU) is a set of image binarization threshold segmentation algorithm, proposed by Japanese scholars ohtsu in 1979.
