how to scan lines vertically?
Hi, Currently im scanning lines in a binary image. The thing is i wanted to scan vertically yet i only found out that the for loop is only scanning it vertically. Here is the example of the code. Is there any way that i could scan the image vertically? I did swap the x and y together with rows and cols but it does not work.
for( int y=0; y< frame_gray.rows; y+=10){
for (int x=0;x< frame_gray.cols;x+=1){
if (frame_gray.at<uchar>(y,x)==0)
{ cout << "0 binary=" << endl;}
else
{ cout << "1 binary=" << endl;}
//waitKey(0);
}
cout << "new pixel line" << endl;
}
