Ridge-Detection for the Perceptual Organization Without Edges,

Abstract

We present a parallel perceptual organization scheme based on a novel ridge detector that works without edges; the scheme computes perceptual groups and potential points which can serve as focus of attention for further processing. The ridge detector finds ridges on vector fields and it is designed to automatically find the right scale of a ridge even in the presence of noise, multiple steps and narrow valleys. One of the key features of such ridge detector is that it has a zero response at discontinuities. The ridge detector can be applied both to scalar and vector quantities such as color.
