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

#include

#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;xwidth;x++)

{

for(y=0;yheight;y++)

{

{

cvSet2D(paintx,y,x,t);

}

}

{

{

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);

cvReleaseImage(&src);

return 0;

}
