| Abstract | Automatic human identification is a hot topic with many applications, mainly in security. A common type of facial features used for the purposes of biometric recognition and identification includes geometrical characteristics. To this respect, the current study is performed on a proprietary dataset of 53 subjects (with several frames per subject) by utilizing 3D geometrical face features extracted from the Euclidean and geodesic intradistances between specific nodal facial points. The objective is to achieve high accuracy in the verification of the IDs of the users. Two feature selection methods based on information criteria are selected and benchmarked herein, i.e. the minimum redundancy and maximum relevance (mRMR) and the conditional mutual information with nearest neighbors estimate (CMINN). The repeated computations on several randomly selected training and test sets from the ensemble of frames give evidence for successful classification of the 53 persons based on a significantly reduced subset of features, where smaller cardinality of the subset is obtained by CMINN. The fact that both methods converge to the same level of classification accuracy when the feature subset increases, proves that high recognition rates can be achieved via only a very small fraction of features. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
