Abstract | Nonlinear distorted fingerprint image matching is a challenge task in most computer-based Auto Fingerprint Identification Systems. Especially for minutiae-based matching algorithm, which is most widely adopted, both the location and direction of the minutiae are changed because of distortion. We carefully observe many distorted fingerprint images, find out some useful characteristics of minutiae' deviation on nonlinear distorted image, and try to use them to improve the matching accuracy. In this paper, we propose a method to adjust the minutiae position and direction on the basis of some landmark minutiae pairs got in pre-processing step. As a result, the minutiae deviation caused by nonlinear distortion can be recovered to a certain extent. Experimental results on FVC2004 DB2 show that our method can improve the matching performance clearly. Also this method can be deployed in most existing minutiae-based Auto Fingerprint Identification Systems easily. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
