We exploit a duallayer loopy belief propagation to minimize the discrete energy function. To speed up the algorithm, a coarsetofine matching scheme is employed as well. b. Given the optimized mapping relation, we define the conditional similarity as, where γ is the scale

This paper proposes a hybrid duallayer approach which constitutes a compromise between SC and SEC, applicable especially to large arrays. Specifically, the array is divided into a number of groups and the switch and examine strategy is leveraged independently within each group.

approximate inference algorithms. Loopy belief propagation is a widely used approximate inference algorithm for graphical models. It works by applying the same belief propagation algorithm designed to compute exact marginal probabilities on singly connected Bayesian networks to those that contained loops. In the second part of this
The theoretical setting of hierarchical Bayesian inference is gaining acceptance as a framework for understanding cortical computation. In this paper, we describe how Bayesian belief propagation in a spatiotemporal hierarchical model, called Hierarchical Temporal Memory (HTM), can lead to a mathematical model for cortical circuits.
Motion Layer Assignment • Assign each pixel to a motion cluster layer, using four cues: –Motion likelihood—consistency of pixel's intensity if it moves with the motion of a given layer (dense optical flow field) –Color likelihood—consistency of the color in a layer –Spatial connectivity—adjacent pixels favored to belong the same
Such network structures are 'loopy' because of the cycles in their underlying graphs. Belief propagation is theoretically guaranteed to give accurate results in nonloopy graphs. Even though theoretical guarantees do not exist for belief propagation in loopy graphs, it is found to work well in practice on many problems involving loops,.

A Comparison of Loopy Belief Propagation and Dual Decomposition for Integrated CCG Supertagging and Parsing Via an oracle experiment, we show that the upper bound on accuracy of a CCG parser is significantly lowered when its search space is pruned using a supertagger, though the supertagger also prunes many bad parses.
