Abstract

The invention relates to a bioassay system based on iris texture analysis, which conquers the defects of existing technic of the absence of iris image quality analysis mechanism support and iris marking image quality evaluation which is not accomplished. The invention is implemented by iris marking image acquisition, automatic iris positioning, evaluation and analysis of iris marking image quality, automatic tracking and detacting of living iris, iris analysis area standardization, polar coordinate transformation, demodulation and expression of iris marking feature, quantizing code generating feature code IrisID, similarity measurement of feature code IrisID, adjudge of similarity measurement. The invention implements basic feature require of idealized system: automatic, non-invasive, friendly human machine operating interface and imaging picture of high quality; no correlation of geometry affine switch and non-linear affine deformation; no dependency of exterior imaging condition; code distributed at random probability; error acceptance rate and error reject rate of high precision.

Description

【Technical field】 [0001] The invention relates to a biometric method based on iris texture analysis, in particular to a method for realizing automatic non-invasive acquisition of high-quality iris images and an individual biometric method based on iris texture analysis, which belongs to biostatistics, pattern recognition and computer vision In the interdisciplinary field, the device used in the method belongs to the technical fields of opto-mechanical-electrical integration and automatic control. 【Background technique】 [0002] Physiological and anatomical medical characteristics of the iris used for individual biometrics are: [0003] 1. The texture of the iris is rich in details; [0004] 2. The formation of iris texture tissue details is related to the environment of the embryonic development stage, which has great randomness, even for monozygotic differentiation; [0005] 3. The characteristics of iris texture tissue remained unchanged from 8 months to 2 years after bi...
