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.

一种用于指纹图像增强和验证的500 dpi蜂窝逻辑处理阵列

500 dpi蜂窝逻辑处理阵列在一个芯片上执行所有指纹识别步骤，从图像采集，增强到验证。用于执行这些步骤的形态学函数在30/spl times/50-/spl mu/m/sup 2/处理单元中实现。单周期数据路径和共享逻辑结构使处理单元的实现更加紧凑。制作的224/spl次/256像素指纹识别LSI具有全功能的图像处理和实用的识别精度。
