perception. We describe a recognition framework to generate a virtual environment through CAD-based vision techniques from optical data. Descriptions of objects of the environment in terms of aspect graphs, and suitable recognition strategies for them are compiled off-line. A relational graph of image features is obtained on-line by processing optical data, and matching occurs between such a graph, and descriptions of objects in the framed scene. Multiresolution techniques are used in order to adapt recognition strategies to the distance and relevance of objects within the field of view.

Abstract
perception. We describe a recognition framework to generate a virtual environment through CAD-based vision techniques from optical data. Descriptions of objects of the environment in terms of aspect graphs, and suitable recognition strategies for them are compiled off-line. A relational graph of image features is obtained on-line by processing optical data, and matching occurs between such a graph, and descriptions of objects in the framed scene. Multiresolution techniques are used in order to adapt recognition strategies to the distance and relevance of objects within the field of view.
