[OpenCV]: match template (cvMatchTemplate)

#include <cxcore.h>
#include <highgui.h>
#include <stdio.h>
int main( int argc, char** argv )
{
IplImage *src, *templ,*ftmp[6]; //ftmp is what to display on
int i;

//Read in the template to be used for matching:
if((templ=cvLoadImage("template.jpg", 1))== 0) {
printf("Error on reading template %s\n","temp");
return(-1);
}

//Read in the source image to be searched:
if((src=cvLoadImage("source.jpg", 1))== 0) {
printf("Error on reading src image %s\n","source");
return(-1);
}

int patchx = templ->width;
int patchy = templ->height;
int iwidth = src->width - patchx + 1;
int iheight = src->height - patchy + 1;
for(i=0; i<6; ++i){
ftmp[i] = cvCreateImage( cvSize(iwidth,iheight),32,1);
}

//DO THE MATCHING OF THE TEMPLATE WITH THE IMAGE
for(i=0; i<6; ++i){
cvMatchTemplate( src, templ, ftmp[i], i);
cvNormalize(ftmp[i],ftmp[i],1,0,CV_MINMAX);
}
//DISPLAY
cvNamedWindow( "Template", 0 );

  1. Thanks! This is really helpful for an image stitching algorithm I'm implementing.
