| Abstract | The performance of an automatic fingerprint authentication system relies heavily on the quality of the captured fingerprint images. The error rates of such systems can significantly be decreased just by detecting and removing poor quality images right at the early stages. In this paper, an effective quality estimation scheme is proposed, which performs analysis in hierarchical fashion. This multilayered quality analysis comprises eight quality measures, three at global level (whole image)) and five at local level (block-wise), each one giving its respective quality score. The scores at their respective levels are fused into a single quality score by their corresponding fusion engines at two different levels. Fusion engines are based on the ‘Weighted Sum rule’. The scheme is also evaluated using ‘Sum rule’. The proposed scheme is experimented against fingerprint Verification Competition (FVC 2004) datasets. The experimental results show that this arrangement could correctly estimate and assign grades (good/acceptable/poor) to nearly 95% images in the dataset. Also, it is observed that this novel fusion-based hierarchical quality assessment model estimates fingerprint quality more effectively with ‘weighted sum rule’ than ‘sum rule’ and their individual counterparts. |

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.
