This article will focus on the skills and demonstrations of OpenCV template matching with mask. (Source Public Account: OpenCV and AI Deep Learning)
Background introduction
When using template matching, in some specific cases, we do not need to match the entire template image, but only need a specific part of it as a template, and adding other parts will affect the matching result. As shown below:
In addition to the part we want, the original template image on the left has an external white background area. If the entire image is used as a template for template matching, the matching result will be wrong, and the result is as follows:
