I am trying to use object detection to recognise a post-it note within a video feed. I am using emguCV for detection. I tried using the Shape Detection approach but it couldn't recognise the post-it... maybe because I was holding it up in the air so my fingers were obstructing the vertices.
I've also tried using SURF detection but that did not work either I guess because it is a square so does not have any stand-out features.
I attempted to use HAAR/LBP classification but it was taking over 10 hours to train just for one stage for 48 positives and 80 negatives so I gave up.
Can anyway suggest a suitable method for detecting/recognising a post-it note within a video feed? Would be much appreciated.
