Curved Inertia Frames Visual Attention and Perceptual Organization Using Convexity and Symmetry
J. Brian Subirana-Vilanova · Defense Technical Information Center (DTIC) · 1991
In this paper we present an approach to perceptual organization and attention based on Curved Inertia Frames (C.I.F.), a novel definition of 'curved axis of inertia'. Such a definition is novel because it is global and can detect curved axes; it can also be used to compute a frame of reference of the shapes in an image useful for non-rigid object recognition or to pull out interesting structures in the image. The scheme assigns a saliency measure to each component of the reference frame that is a measure of its relevance, so that large, smooth, convex, symmetric and central parts play a more central role in the description of the shape. One of the remarkable features of the scheme is its tolerance to noisy and spurious data.... Vision.
