College Entrance Examination Fingerprint Identification System

Common University solicit students examination is a national examination. It is concerned deeply by the society. For creating a good examination environment for all the students, guaranteeing the authority of the national education examination, we developed "Common University solicit students examination fingerprint identify system" based on Biokey SDK.On the process of the software development, we find that it is difficult to "align" the pictures. So we put forward matrix correlation theories and based on the correlation coefficient of matrixes, we put forward feature district searching algorithm.Based on unpretreatment pictures, we carried on feature district searching algorithm experiment. Experiment results proved that this algorithm is efficient and accurate. If we carry on a picture pretreatment such as gray transform, standardize, unitary in advance, the effect will be more ideal.We make use of this algorithm in the fingerprint identify realm and development "Common University solicit students examination fingerprint identify system". And apply it in Common University solicit students examination successfully.This article main research results, as follows:1) Scientific design "Common University solicit students examination fingerprint identify system".2) Reform the database of the center of solicit students examination and add fingerprint identify information.3) According to the correlation theories of vectors, we put forward matrixes correlation theories and the feature district searching algorithm.4) Using the algorithms and tools we develop the software of fingerprint identify.
