QuestionImage processingmemberfabio_antonio23 Sep '12 - 8:25 
Hi, I have some troubles recognizing some shapes in some images I have. The objective of the app I am trying to make is to recognize the open shapes (circles or squares) in a given image. I can do it when the shapes don't overlap each other, but sometimes they do and I can't recognize them accurately. Here are some samples to understand the problem:

Thanks for any suggestion. And sorry if my english is not so good.

The Hough Transform (http://en.wikipedia.org/wiki/Hough_transform[^] ) is useful for recognizing incomplete images.
