Hello experts,
I have this code which works so perfect while detecting square objects from images which are downloaded from internet. However, when I am taking the image of a square object from my webcam and processing, its not turning out to be as expected. I am suspecting, the reason could be due to the green and pink hues which are dominantly captured from webcam. The actual output which is being obtained is that there are squares distributed at random places. What do you all suggest?

I suggest you upload an image: http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers It's always easier to discuss image image processing advice if you have an image to see, don't you think?

I am sorry, I meant circular and not square. I am really sorry for this mistake.

You can edit your post to correct it. Have you tried imfindcircle()?

I have actually tried everything with the code along with the parameters of imfindcircle and I am completely confident that everything is perfect. However, I would only agree with one of your point which is poor lighting.

I don't know why you don't agree with the other 3 points, but whatever...
