On the Role of Contrast and Regularity in Perceptual Boundary Saliency

Mostrar todas las versiones(2)

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...
