In this paper, we extend selective attention to guide contour extraction prepared for perceptual grouping. Selective attention functions in two aspects.

Model selection, which means selecting a suitable model from a class of plausible candidate models to explain the given data, is important in almost every field of scientific research including visual perception process. In fact, model selection bears a striking similarity to visual perception in view of inverse problem, and model selection is an all-pervading problem in visual perception. This paper...
