喜欢素描，最近又开始玩一点简单的OpenCV，整好有个例子是把图片灰度化的。就专门记录一下，这算是serendipity吧~
#include "cv.h"#include "highgui.h"int main ( int argc, char **argv ){IplImage *pImg; //声明IplImage指针//载入图像，强制转化为Grayif ( argc == 3 && ( pImg = cvLoadImage ( argv[1], 0 ) ) != 0 ){IplImage *pImg2 = cvCreateImage ( cvGetSize ( pImg ), pImg->depth, pImg->nChannels );cvCopy ( pImg, pImg2, NULL );cvSaveImage ( argv[2], pImg2 );//把图像写入文件cvNamedWindow ( "Image", 1 );//创建窗口cvShowImage ( "Image", pImg );//显示图像cvWaitKey ( 0 ); //等待按键cvDestroyWindow ( "Image" );//销毁窗口cvReleaseImage ( &pImg ); //释放图像cvReleaseImage ( &pImg2 ); //释放图像return 0;}return -1;}
