Abstract
A 500-dpi cellular-logic processing array performs all fingerprint identification steps on one chip, from image acquisition, enhancement, to verification. Morphological functions for executing these steps are implemented in a 30/spl times/50-/spl mu/m/sup 2/ processing unit. A single-cycle datapath and a shared logic structure enable compact implementation of the processing unit. A fabricated 224/spl times/256-pixel fingerprint identification LSI demonstrates fully-functional image processing and practical accuracy of identification.
