<title>Experiments with perceptual grouping</title>

Abstract

Perceptual grouping of image features are groups of 2D image features which possess properties that reflect their 3D strucwres they are useful for matching 2D image features to 3D models. In this paper perceptual grouping experiments based on cyclically connected loops and partially out-of-view loops are performed. Results can be applied to separate individual objects in the scene filtering out noise and pruning the search space for matching the image features to model features.
