Recognition of 3D objects in arbitrary pose using a fuzzy associative database algorithm

Abstract

Once the human vision system has seen a 3D object from a few different viewpoints, depending on the nature of the object, it can generally recognize that object from new arbitrary viewpoints. This useful interpolative skill relies on the highly complex pattern matching systems in the human brain, but the general idea can be applied to a computer vision recognition system using comparatively simple machine learning techniques. An approach to the recognition of 3D objects in arbitrary pose relative to the vision equipment with only a limited training set of views is presented. This approach involves computing a disparity map using stereo cameras, extracting a set of features from the disparity map, and classifying it via a fuzzy associative map to a trained object. © 2011 IEEE.
