OpenCV学习_1和总结

       昨天晚上开始突然想学一下图像学什么的，于是去隔壁找了JJ牛——在此真的很感谢JJ对我的帮助和对我傻×的无限忍耐。。。

        先是codeblocks，准确说一直在配置它的一些设置，今天下午又试试了DEV，然后又是QT。。。均以失败告终——Process terminated with status -1073741510 。

        实在没办法的时候转机出现了。。。最后改了下设置，在QT下运行成功了！

        代码参考网上的：

#include <highgui.h>#include <cv.h>int main(int argc, char* argv[]){    cvNamedWindow("in");    IplImage* in = cvLoadImage(argv[1]);    IplImage* r = cvCreateImage(cvGetSize(in), IPL_DEPTH_8U, 1);    IplImage* g = cvCreateImage(cvGetSize(in), IPL_DEPTH_8U, 1);    IplImage* b = cvCreateImage(cvGetSize(in), IPL_DEPTH_8U, 1);    IplImage* out = cvCreateImage(cvGetSize(in), IPL_DEPTH_8U, 1);    IplImage* dst = cvCreateImage(cvGetSize(in), IPL_DEPTH_8U, 1);    cvSplit(in, r, g, b, NULL);    cvAddWeighted(r, 1./3., g, 1./3., 0, out);    cvAddWeighted(b, 1./3., out, 2./3., 0, out);    cvNamedWindow("out");    cvShowImage("out", out);    cvThreshold(out, dst, 150, 255, CV_THRESH_BINARY);    cvNamedWindow("dst");    cvShowImage("dst", dst);    cvShowImage("in", in);    cvWaitKey(0);    return 0;}

PS：我就是一笨蛋，笨的不行！

结束抄代码！开始自己写！加油！
