Research Of Fingerprint Mosaicking Algorithm Based On Phase Correlation

Biometrics identification refers to identifying an individual based on her physiological or behavioral characteristics instead of knowledge-based and token-based techniques. It is a more reliable and capable method because the physiological or behavioral characteristics are unique to every person. Fingerprint identification has become one of the most popular, more feasible and more reliable techniques to realize personal identification with the essential character of fingerprint: uniqueness, permanence and high performance. Especially, the state-solid sensor which can be embedded into other devices easily leads to the rapid development of automatic fingerprint identification system.Although a number of systems and products based fingerprint has been developed by the long-term research and development of fingerprint identification technique, there is still some limits to cater for certain application. Embedding is demanding a smaller size of fingerprint sensor; the area of sensor must be smaller in order to cut off the price to win the dramatic marketing competence. Fingerprint identification is facing a serious challenge lacking of effective in fingerprint image due to the smaller area of sensor. In the paper, a fast fingerprint mosaicking algorithm based on phase correlation is proposed focusing on enlarging the area of fingerprint image and increasing effective information of fingerprint image. It not only realizes the mosaicking of fingerprint image, but also implements the mosaicking of fingerprint sequence image accurately.The thesis is organized as follows:Chapter one introduces the history and current situation of biometric and the main...
