This paper introduces a new biologically inspired technique that retrieves scene surface information. The human eye provides the inspiration for this technique. Human vision essentially comprises peripheral and foveal vision. Information processing under peripheral vision is very fast since fewer features are sensed. Peripheral vision provides guiding information for the subsequent foveal analysis. Foveal vision involves a high resolution examination of a particular region of the scene. The biologically inspired technique involves a pyramid hierarchy that provides the platform for three-dimensional reconstruction at different resolution levels. Three-dimensional reconstruction is based on a cue combination process that involves feature-based stereo, occlusion, and visible surface reconstruction. The technique enables fine resolution surface information to be obtained for a specified region of interest which is surrounded by coarse resolution surface information. Experimental results are presented to illustrate the performance of this technique.
