OpenCV学习笔记_cvCircle, cvAnd, cvOr, cvSetIdentity使用

#include <cv.h>#include <highgui.h>using namespace std;int main(void){IplImage* image = cvLoadImage("d:\\2.jpg");IplImage* src = cvCreateImage(cvGetSize(image), IPL_DEPTH_8U, 3);cvZero(src);cvNamedWindow("Test", CV_WINDOW_AUTOSIZE);cvShowImage("Test", src);int min = (src->width / 2) > (src->height / 2) ? (src->height / 2) : (src->width / 2);cvCircle(src, cvPoint(min, min), min, cvScalar(255, 255, 255), CV_FILLED, 8, 0);cvAnd(image, src, src);cvShowImage("Test", src);cvShowImage("Test1", image);cvWaitKey(0);cvSetIdentity(src);cvOr(image, src, src);cvShowImage("Test", src);cvWaitKey(0);return 0;}
