Matching with pattern — it is a method of finding areas of an image similar to a patch (pattern).
Patch — it is a small image with certain functions. The target of pattern matching — find the patch / pattern in the image.
To find it, the user must provide two input images: original image (S) — the image in which to find the template, and the template image (T) — the image to be found in the original image.
How does templating work?
Template matching constraints:
To avoid the problem caused by different template and source image sizes, we can use multiscale . In cases where the dimensions of your template do not match the dimensions of the area of the image you want to match, that does not mean that you cannot apply template matching.
The multiscaling mechanism in the match pattern
The Multi Scaling process looks like this:
