Genericity and junctions in motion interpretation

Junctions and cost functions in motion interpretation.

Form, motion, occlusion, and perceptual organization are intimately related. We sought to assess the role of junctions in their interaction. We used stimuli based on a cross moving within an occluding aperture. The two bars of the cross appear to cohere or move separately depending on the context; in accord with prior literature, motion interpretation depends in part on whether the bar endpoint...

Beyond junctions: nonlocal form constraints on motion interpretation.

Because of the aperture problem, local motion measurements must be combined across space. However, not all motions should be combined. Some arise from distinct objects and should be segregated, and some are due to occlusion and should be discounted because they are spurious. Humans have little difficulty ignoring spurious motions at occlusions and correctly integrating object motion, and are ev...

Interpretation and Computation of alpha-Junctions for Combining Belief Functions

The α-junctions are the associative, commutative and linear operators for belief functions with a neutral element. This family of rules includes as particular cases the unnormalized Dempster’s rule and the disjunctive rule. Until now, the α-junctions suffered from two main limitations. First, they did not have an interpretation in the general case. Second, it was difficult to compute a combinat...

Cosets and genericity

In a connected group of finite Morley rank in which the generic element belongs to a connected nilpotent subgroup, proper normalizing cosets of definable subgroups are not generous. We explain why this is true and what consequences this has on an abstract theory of Weyl groups in groups of finite Morley rank. The only known infinite simple groups of finite Morley rank are the simple algebraic g...
