This paper describes a visual perception system which allows a social robot to conduct several tasks. The central part of this system is an artificial attention mechanism which is able to discriminate the most relevant information from all the visual information perceived by the robot. This attention mechanism is composed by three modules or stages. At the preattentive stage, a set of uniforms blobs...
Robot learning by imitation has become a key topic in robotics research in the last years, due to the increasing interest in social robots. While several architectures that deal with this topic have been proposed, few efforts have been done in finding unified formats that may help in analyzing and comparing these architectures. This paper firstly proposes a set of components that can be identified...
This paper presents a new technique to extract objects from a real complex background so that a video sequence can be decomposed into a set of objects as required for object oriented video compression techniques. The proposed method is based on a background subtraction technique. However, instead of using a fixed background, the system relies on predicting one from a previously constructed virtual...
