I'm wondering if any one can help with recognizing a marked pig using a webcam image.image description The pigs wil go trough a sorting system and only those marked need to be sorted.

I rather have one small dot, than a complete painted pig :)

Looking forward to your suggestions.

Who can create such a "tool" for example running on a beagle bone board? I'm not familiar with image processing :(

WE HAVE DEVELOPED A SOLUTION FOR THE SORTING BASED ON COLOUR. THIS SO CALLED SORTI CAM HAS BEEN DEPLOYED IN OVER 30 STABLES AND WORKS VERY WELL. ONLY A SMALL DOT OF BLUE PAINT IS ENOUGH TO SORT THEM. SO IF ANY ONE IS INTERESTED, MAIL US: ID@DORSET.NU

unfortunately not all pigs are marked this clearly. A big dot would even be better if that could be detected.

Any one an idea?

it still can work, if the range is enough large.

Based on what we see, you should be able to isolate the pigs using skin color and then, look for the markings in the isolated cases.

If it is always marked with blue, and you do not have any blue in the background, it is a simple matter of converting to HSV and perform an inrange threshold to separate blue pixels.
