Digital three-dimensional object reconstruction and recognition using integral imaging

Abstract

Integral images contain three-dimensional (3D) information about a scene. We extract this information using a stereo-matching algorithm and we digitally reconstruct the 3D scene in a computer. We then use the reconstructed scene to perform 3D recognition by means of a nonlinear 3D correlation. We demonstrate the recognition and localization of objects in a 3D scene. We also compare discrimination of 2D and 3D correlations.
