Object Labelling is the goal of uniquely labelling each pixel as being part of a connected object. It is related to the tasks of segmentation and thresholding, but when binary images are being discussed the task is usually refered to as labelling.

DifficultiesEdit

This apparently has a simple problem is probably the best illustration for the novice of some of the fundamental difficulties of doing vision on a serial computer. The Human Visual System can instantly perform counting with deceptive effortlessness. To understand the difficulty of getting a computer to do the same, remember that a computer can only 'look' at one pixel at a time. Try counting objects while looking at the world through a straw! It soon becomes clear that this needs an iterative solution.
