本程序对身份证的图像提取并进行二值化得到黑白对比度处理后的身份证ostu算法-The ID card program for image extraction and binarization to be black and white contrast of the processed ID ostu algorithm

Ostu算法在图像分割中的应用,即二值化处理-Ostu image segmentation algorithm in the application, that is, to deal with binary

输入为灰度图，输出为二值图。函数功能是通过ostu找到阈值后，根据一定策略来滤除孤立点，加强密集点。-Grayscale input, output for the binary image. Function ostu found through the threshold, in accordance with a certain strategy to filter out isolated points, to strengthen the point-intensive.
