Pictorial Representation of Loopy Belief Propagation Message Passing for Stereo Matching

<div>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.</div><div><br></div><div>Both formats are the same image, they are both included for your convenience, and because figshare apparently doesn't render .eps files in-browser but .eps seems to be the required vector graphics format for many publications.<br></div>
