This paper introduces a new method to represent the surface of objects using two dimensional com-binatorial maps. The classical definition of two dimensional combinatorial maps is extended here by adding a " back face " that corresponds to the non–visible part of the object. As a first step, every object in the scene is extracted in one image pyramid, where(More)
This paper describes a visual landmark detection and description system for mobile robotic environment mapping. At the detection stage, the proposal employs a perceptual-based hierarchical mechanism which has been previously used to successfully solve the segmentation of natural images. At the description stage, visual landmarks are characterized by a(More)
In biological vision systems, attention mechanisms are responsible for selecting the relevant information from the sensed field of view, so that the complete scene can be analyzed using a sequence of rapid eye saccades. In recent years, efforts have been made to imitate such attention behavior in artificial vision systems, because it allows optimizing the(More)
