A computer-based integrated imaging system (CIIS) using normalized cross correlation (NCC) for resolution enhancement is proposed to extract accurate location data of 3-D objects. Elemental images (EI) of the target and reference objects are picked up by lenslet arrays, and then target and reference plane images with enhanced resolution are reconstructed at the output plane by using the CIIS technique. Through cross correlations between the reconstructed reference and target plane images, 3-D location data of the target objects in a scene can then be robustly extracted. As a result of our experiments, we see that the proposed correlation scheme provides good discrimination and detection performance for 3-D object recognition.
