Model and Implementation of Large Scale Fingerprint Image Retrieval

Since the 21st century, along with the continuous renewal of digital image acquisition equipment and popularization, the number of the fingerprint image data of explosive growth, one to one matching for fingerprint identification method seriously affect the efficiency of fingerprint database system identification, vlsi fingerprint database retrieval problem be theres an urgent need to solve a problem. Therefore, it is necessary to introduce the pre screening technology, that is, image retrieval technology, design an efficient and accurate search algorithm to eliminate as much as possible in the large scale database with the query fingerprint image does not have the same relationship of the image, reduce the fingerprint matching space. After such retrieval process, relatively few fingerprints in the database and query fingerprints have a high degree of similarity, and then the one to many comparison mode is adopted to compare and match one by one, which can effectively reduce the time used in the whole identification process. In view of this, the design of efficient and accurate search algorithm has become one of the focuses of large scale fingerprint image retrieval.
