基于特征描述子的匹配方法

Abstract

Abstract:

A fingerprint identification method based on the characteristic descriptor is proposed.This method has high efficiency and matching and small storage space.By this method fingerprint matching is realized and applied to the embedded system.Because automatic fingerprint identification is usually realized in an embedded system,it has a high requirement on the complexity,calculation speed and storage space of an algorithm.Therefore,a popular characteristic based matching method is used.This algorithm is fast in calculation.Experiments show that this algorithm has the advantages of simple calculation,high speed easy determination of the reference point and good robustness on the rotation and translation of the image.By this algorithm,the matching of the characteristics of the random local descriptor based on the characteristic descriptor can be improved.

Key words: AFIS;singular point of a function;characteristic descriptor;fingerprint matching
