Abstract

One of the first steps of any visual system is that of locating suitable interest points, `salient regions', in the scene, to detect events, and eventually to direct gaze toward these locations. In the last few years, object-based visual attention models have received an increasing interest in computational neuroscience and in computer vision, the problem, in this case, being that of creating a model of `objecthood' that eventually guides a saliency mechanism. We present here an model of visual attention based on the definition of `proto-objects' and show its instantiation on a humanoid robot. Moreover we propose a biological plausible way to learn certain Gestalt rules that can lead to proto-objects.
