Template Matching

It convolves the search image with the one being search into. Because the resolution of document images is 100 dots per inch, using methods based on contour matching and ocr is not useful. It is usually used to find smaller. Any result that the you get i.e. How to perform scale and rotation invariant template (feature) matching and object detection.

Use the template as kernel and filter the image. The best and easiest solution for. Template matching a good example here matchtemplate finding good match. The scan area is reduced by the size of the template). The matching process slides the template across the image, comparing at every pixel.

In fact, it will be so cheap, that you can also rotate your template roughly on the low resolution levels, and when you trace the template back down to the higher resolution. You'll have to cluster the results (e.g. I have been trying to use opencv's template matching function to match templates within images. However, when the images are dark.

A match point is actually a reference to the top left corner of the template so to find the centre of your match simply subtract half the template. The destination mat will have dense bright areas where your template might be. It convolves the search image with the one being search into. Because the resolution of document images is 100.
