自适应阈值opencv

Question

大家好我使用cvAdaptiveThreshold有人可以解释我如何工作这个函数如何确定block_size和param1？

IplImage *imgPicThres = cvCreateImage(cvSize(img_roi->width, img_roi->height), IPL_DEPTH_8U, 1); 

cvAdaptiveThreshold(img_roi, imgPicThres,255,CV_ADAPTIVE_THRESH_MEAN_C, CV_THRESH_BINARY_INV,blocks_size,param1); 

Answer 1

cvAdaptiveThreshold()是described in the documentation：

It transforms a grayscale image to binary image。
