I need a library that can detect objects in an image (uses edge detection).

I need a library that can detect objects in an image (uses edge detection). This is NOT related to captchas. I am working on an MTGO bot that uses OCR and that works in any screen resolution. In order for it to port to any screen resolution my idea is to scan down narrow range on a results page (the cards that a player has can be listed in rows of text) and to find each object in that range. Then to take the lowest and highest pixel coordinates of each object to find where the row starts and ends (on the y axis) so that I can use OCR to read each line.

  1. If you don’t know of the OpenCV collection of examples, then they could help you in the right direction… there’s also Camellia which doesn’t use ‘edge detection’ per-se but could get the results you need with a bit of work.
