本文实例为大家分享了OpenCV计算图像的水平和垂直积分投影的具体代码，供大家参考，具体内容如下

#include <cv.h> #include <highgui.h> #pragma comment( lib, "cv.lib" ) #pragma comment( lib, "cxcore.lib" ) #pragma comment( lib, "highgui.lib" ) int main() { IplImage * src=cvLoadImage("lena.jpg",0); //cvSmooth(src,src,CV_BLUR,3,3,0,0); cvThreshold(src,src,50,255,CV_THRESH_BINARY_INV); IplImage* paintx=cvCreateImage( cvGetSize(src),IPL_DEPTH_8U, 1 ); IplImage* painty=cvCreateImage( cvGetSize(src),IPL_DEPTH_8U, 1 ); cvZero(paintx); cvZero(painty); int* v=new int[src->width]; int* h=new int[src->height]; memset(v,0,src->width*4); memset(h,0,src->height*4); int x,y; CvScalar s,t; for(x=0;x<src->width;x++) { for(y=0;y<src->height;y++) { s=cvGet2D(src,y,x); if(s.val[0]==0) v[x]++; } } for(x=0;x<src->width;x++) { for(y=0;y<v[x];y++) { t.val[0]=255; cvSet2D(paintx,y,x,t); } } for(y=0;y<src->height;y++) { for(x=0;x<src->width;x++) { s=cvGet2D(src,y,x); if(s.val[0]==0) h[y]++; } } for(y=0;y<src->height;y++) { for(x=0;x<h[y];x++) { t.val[0]=255; cvSet2D(painty,y,x,t); } } cvNamedWindow("二值图像",1); cvNamedWindow("垂直积分投影",1); cvNamedWindow("水平积分投影",1); cvShowImage("二值图像",src); cvShowImage("垂直积分投影",paintx); cvShowImage("水平积分投影",painty); cvWaitKey(0); cvDestroyAllWindows(); cvReleaseImage(&src); cvReleaseImage(&paintx); cvReleaseImage(&painty); return 0; }

结果：
