opencv彩色图转换为灰度图并保存

#include "cv.h" #include "highgui.h" int main() { IplImage *src = 0;//原图像 IplImage *dst = 0;//处理后的图像 src = cvLoadImage("src.jpg",1); dst = cvCreateImage(cvSize(src->width,src->height),8,1); cvCvtColor(src,dst,CV_BGR2GRAY); cvSaveImage("dst.jpg",dst); cvNamedWindow( "source", 1 ); cvNamedWindow( "result", 1 ); cvShowImage( "source", src ); cvShowImage( "result", dst ); cvWaitKey(0); cvDestroyWindow("source"); cvDestroyWindow("result"); cvReleaseImage( &src ); cvReleaseImage( &dst ); return 0; }
