I want to use code like below, how can I work with Mat_?
void diff(Mat_ src, Mat_ tmp)
{
int w_s= src.cols;
int h_s= src.rows;
int w_t= tmp.cols;
int h_t= tmp.rows;
double min_peak=INT_MAX;
Point pt;
for(int y=0;y<h_s-h_t+1;++y)
{
for(int x=0;x<w_s-w_t+1;++x)
{
__int64 sum=0;
for(int cy=0;cy<h_t;++cy)
{
for(int cx=0;cx<w_t;++cx)
{
sum+= abs(src[y+cy][x+cx]-tmp[cy][cx]);
}
}
double diff= (double)sum/(w_t*h_t);
if (diff<min_peak)
{
pt.x= x;
pt.y= y;
min_peak=diff;
}
}
}
cout<<pt.x<<" "<<pt.y<<"\n";
}
