The different paper demostrating the superiority of the current model in accounting for perceptual data is the Part II paper previously mentioned, i.e.

Computational Implications of Gestalt Theory II: A Directed Diffusion to Model Collinear Illusory Contour Formation

Had the present paper been accepted for publication, I would have submitted the Part II paper next. However since this paper was rejected all by itself, I guess I won't have the opportunity. There are some ideas which are just too big to fit conveniently in a single paper.
