| Abstract | In this paper, we present a novel adaptively automated fingerprint classification scheme, which is computationally efficient and resolves both intra-class diversities and inter-class similarities. Initially, preprocessing of fingerprint images is carried out to enhance the image. For classification based on global shape, directional image is computed. Principal component analysis is employed in first stage for dimensionality reduction and to get feature space that accounts for as much of the total variation as possible. In second stage, self-organizing maps are involved for further dimension reduction and data clustering. We use the Kohonen topological map for pattern classification. The learning process takes into account the large intra class diversity and the continuum of fingerprint pattern types. Finally LVQ2 maps the class separated fingerprint images into their respective class, the winner and runner-up neuron are trained in such a way that they take into account the inter-class similarities. Experimental results show that AAFFC achieves an accuracy of around 89 % for five-class classification tested on NIST 4 without rejection |

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.
