Hi everyone!
I'm working on a project and I want to select a ROI with my mouse.
Then I want to do the following things:
- Make everything on the outside of the rectangle zero/black.
- Perform some thresholding functions in the ROI.
- Put it back in to the original image.
I don't know how to achieve this. Here's some pseudo code:
for loop to iterate through image{
{
if(point x and y are not the same as the roi x and y ){
make the pixel black
}
}
..perform some thresholding on ROI..
//copy roi back to image
image.copyTo(result, roi);
Can someone help me out here?
Thanks.
