using openCV to recognize a rectangular object.
I'm using openCV with the example of "http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en". I did succeeded using the Haar cascade which I used to detect eyes, nose, mouth etc.
However i need to recognize a rectangular object (like an IDcard) I did some research on this Haar cascade to recognize an IDcard but making my own Haar cascade xml file is a pain in the ***. (needed at least 3000 images to make one).
So I'm stuck at the beginning with recognizing objects. Is there anyone that can help me out with detecting a card with the iphone camera by means of the openCV library.
Help is greatly appreciated
