Finding number of colored shapes from picture using Python

http://stackoverflow.com/questions/5298884/finding-number-of-colored-shapes-from-picture-using-python

the best one Take a picture and start iterating through pixels checking each one's colour. If that is red check all 8 nearest.. each one's colour. If that is red check all 8 nearest pixels recursively check each red one's neighbours again until no more.. red one's neighbours again until no more neighbouring red pixels are found. Then increment nuclei count by one and mark traversed..
