Patent Searching and Data


Title:
ドベシィウェーブレット変換を用いた虹彩認識方法
Document Type and Number:
Japanese Patent JP2004527832
Kind Code:
A
Abstract:
Disclosed is a method of recognizing human iris using Daubechies wavelet transform, wherein the dimensions of characteristic vectors are reduced by extracting iris features from inputted iris image signals through the Daubechies wavelet transform, binary characteristic vectors are generated by applying quantization functions to the extracted characteristic values so that utility of human iris recognition can be improved since storage capacity arid processing time thereof can be improved since storage capacity characteristic vectors, and a measurement process suitable for the low capacity characteristic vectors is employed when measuring vectors and previously registered characteristic vectors.
