Retina recognition by using joint transform correlator (JTC) with JPEG-compressed target and reference images is proposed. Recognition performance is studied by using retina images with different contrasts employed as test scenes. The simulation results show that regardless of the reference contrast, the compression-based JTC offers better recognition performance for a high-contrast target. The compression of target images has advantages in that recognition degradation caused by noise can be reduced and image transfer time delay can be accelerated.
