Empirical constraints for perceptual modeling

Using Perceptual Constraints

We treat sparse “clouds” of non-oriented points, oriented points, and partial surfaces, in a uniform and non-iterative way. We are able to handle scenes of any genus, any number of discontinuities, and of any number of objects, without a priori knowledge or special considerations. The result is in the form of three dense saliency maps for surfaces, intersections between surfaces, and 3-D juncti...

Empirical Evidence for Perceptual Control Theory

Reports results of the use of the Gathering program, a computer simulation based on the principle of perception control theory, on C. McPhail and R. Wolstein's collective locomotion experiment. The program was used to explain purposive individual and collective locomotion behavior found in the experiment. Ss in five 12-person treatment groups were given a set of instructions, similar to those u...

Perceptual modeling for stereoscopic 3D

Virtual and Augmented Reality applications typically rely on both stereoscopic presentation and involve intensive object and observer motion. A combination of high dynamic range and stereoscopic capabilities become popular for consumer displays, and is a desirable functionality of head mounted displays to come. The thesis is focused on complex interactions between all these visual cues on digit...

Perceptual constraints in phonotactic learning.

Structural regularities in language have often been attributed to symbolic or statistical general purpose computations, whereas perceptual factors influencing such generalizations have received less interest. Here, we use phonotactic-like constraints as a case study to ask whether the structural properties of specific perceptual and memory mechanisms may facilitate the acquisition of grammatica...
