Title: Image Detection
Post by: diseasedtoe on January 23, 2012, 01:29:04 am

Hey guys,
I was wondering if you could help me with a challenge I am facing.  I want to create a program that can detect an image in a scene, and put a box around it.  A simple example: If I had a white piece of paper with a black square on it, I would take a picture of it and my program would detect the black square and put a box around it.  Could you please point me in the right direction as to how I could approach this problem?

There is no really easy way to do such a thing. This is an area where computers are still far behind humans.

There is a library you can download and test.

Thank you for replying on such short notice.  I will look through all the libraries and try to figure out which will work best for me.

If you're asking about automatic pattern recognition you should know that this is an NP-difficult problem and an active academic topic. This journal has .PDF articles on the topic:

It is a very complex problem and you will not get the answer in this forum.
