On the role of contrast and regularity in perceptual boundary saliency
Resumen:
Mathematical Morphology proposes to extract shapes from images as connected components of level sets. These methods prove very suitable for shape recognition and analysis. We present a method to select the perceptually significant (i.e., contrasted) level lines (boundaries of level sets), using the Helmholtz principle as first proposed by Desolneux et al. Contrarily to the classical formulation by Desolneux et al. where level lines must be entirely salient, the proposed method allows to detect partially salient level lines, thus resulting in more robust and more stable detec- tions. We then tackle the problem of combining two gestalts as a measure of saliency and propose a method that rein- forces detections. Results in natural images show the good performance of the proposed methods.
