THE USE OF PERCEPTUAL ORGANIZATION IN THE PREDICTION OF GEOMETRIC STRUCTURES

A strategy is proposed for detecting geometric structures by perceptual organization, without prior knowledge of the image contents. A saliency criterion has been defined, that involves the length and the luminance contrast of the edges of an image. Starting from the most salient edges, perceptual organization guides the prediction of the geometric structures that are suggested by parallelism and connectivity relationships. This strategy allows an efficient analysis of the large amount of image features, pointing out at first the main structures present in the scene.
