Abstract

The invention provides an iris identifying system and a realizing method based on field programmable gate array (FPGA) which uses FPGA chip of Altera company as a main control chip, an iris collecting device, a LCD screen and a PS/2 keyboard compose a hardware platform with integrated system. The whole system can realize functions of collecting iris image, displaying iris image, evaluating iris image quality, recording iris object and identifying iris object, wherein, a novel, simple and rapid localization algorithm is provided in iris object recording and iris identifying processes. The iris characteristic extracting algorithm uses two-dimension Gabor filter algorithm for realizing perfect characteristic extraction. The accurate iris localization effect and special characteristic extraction algorithm realize the iris identifying system with high identifying rate and high reliability for authentication.

Description

technical field [0001] The invention belongs to the technical field of biological feature identification, i.e. the technical field of iris identification, and in particular relates to an iris identification method and system based on a Field Programmable Gate Array (FPGA). Background technique [0002] As people move into the digital age, there is an ever-increasing demand for accuracy and convenience in identity verification methods. Traditional identity verification methods mainly include identity markers (such as keys, certificates, etc.) together with identity marker information (such as account numbers, passwords, etc.), or a combination of the above two (such as bank cards, etc.). People find in the process of using that they all have the same shortcoming: they are easy to be lost and forged. Moreover, the traditional identity verification system cannot effectively identify whether the person holding these identity marks is the real owner. Therefore, once it is imper...
