Matching template images with masks using OpenCV and C++

问题

How can I match a masked image using matchTemplate() in OpenCV with C++?

This is my masked template image:

And this is my source image:

回答1:

Look at opencv example. You gotta call the matchTemplate function:

matchTemplate( img, templ, result, match_method );

回答2:

matchTemplate's fifth argument is a mask array which you can use for this purpose. In your case, you'll want a binary mask. That is, a Mat with:

• depth CV_8U, and
• dimensions equal to your template image, and
• the pixels you want to ignore from your template set to 0, and
• the pixels you want to be used set to a non-zero value (typically 1)
