Pictorial representation of the concept behind Loopy Belief Propagation for Stereo Matching. The symbols in the central cell refer to sum-product Belief Propagation, one of the earliest and mostly widely discussed forms of Belief Propagation. Each cell sends a new message to its neighbouring cells at each iteration after in turn having received and processed new messages from the neighbours in the previous iteration. The outgoing message to a given neighbour is computed from the information received from the other neighbours previously, represented here by the three thin and one fat arrow.
