程序：

關鍵函數：cvCmp和cvCmpS

代碼：

#include?"cv.h" #include?"cxcore.h" #include?"highgui.h" #include?<iostream> int?cmp(int?argc,char**?argv) { IplImage*?src1=cvLoadImage("e:\\picture\\3.jpg",0); IplImage*?src2=cvLoadImage("e:\\picture\\11.jpg",0); CvRect?RectROI=cvRect(200,200,300,300);?//設置感興趣區域 cvSetImageROI(src1,RectROI); cvSetImageROI(src2,RectROI); cvNamedWindow("Src1ROI"); cvNamedWindow("Src2ROI"); cvShowImage("Src1ROI",src1); cvShowImage("Src2ROI",src2); IplImage*?dst=cvCreateImage(cvSize(300,300),8,1); cvZero(dst); IplImage*?dst2=cvCreateImage(cvGetSize(src1),8,1); cvZero(dst2); cvCmp(src1,src2,dst,CV_CMP_GT); cvCmpS(src1,80,dst2,CV_CMP_LT); cvResetImageROI(src1); cvResetImageROI(src2); cvNamedWindow("result"); cvShowImage("result",dst); cvNamedWindow("result2"); cvShowImage("result2",dst2); cvWaitKey(0); cvDestroyWindow("Src1ROI"); cvDestroyWindow("Src2ROI"); cvDestroyWindow("result"); cvDestroyWindow("result2"); cvReleaseImage(&src1); cvReleaseImage(&src2); cvReleaseImage(&dst); cvReleaseImage(&dst2); return?0; }
