Abstract

The invention provides a negative sample selection method in biometrics identification and an apparatus thereof so as to solve a misrecognition problem in the biometrics identification. The method comprises the following steps: determining distribution of existing negative samples in a sample space; determining a negative sample number N to be selected; selecting the negative sample with the largest dispersion between the N negative samples in the existing negative samples. By using the negative sample selection method based on space dispersion analysis, under the condition of the certain negative sample number, the negative sample which can cover the face space most and most effectively reduce a misrecognition rate can be selected from the existing negative samples. Face authentication system performance can be raised. In addition, the method and the apparatus of the invention are also suitable for other bioinformation identity authentication systems, wherein the other bioinformation comprises: fingerprints, irises and the like.

Description

technical field

[0001] The invention relates to the technical field of pattern recognition, in particular to a method and device for selecting counter samples in biological feature recognition. Background technique

[0002] Biometric recognition technology is a science that utilizes individual's unique physiological and behavioral characteristics to achieve identity recognition and (or) individual verification purposes, such as recognition of face, fingerprint, palm print, iris, voice, etc. In the biometric identification technology, the recognition technology characterized by human face has developed very rapidly in recent years.

[0003] With the development of face recognition technology, face recognition-related application systems are gradually increasing. As an application system related to face recognition technology, face authentication systems have achieved more and more applications in automatic access control, face login, etc. . The face authentication system us...
