| Abstract | In this paper, a method of two dimensional Fisher principal component analysis (2D-FPCA) in the two dimensional principal component analysis (2DPCA) transformed space is analyzed and its nature is revealed, i.e., 2D-FPCA is equivalent to 2DPCA plus two dimensional Fisher linear discriminant analysis (2DFLD). Based on this result, a more transparent 2D FPCA algorithm is developed. That is, 2DPCA is performed first and then 2DFLD is used for the second feature extraction in the 2DPCA transformed space. Since 2D FPCA is based on the 2D image matrices, the vectorization of the image is not required. Thus, 2D FPCA optimizes the evaluation of the image matrices, the between and within matrices, by transforming them into a smaller 2DPCA space. In the linear discriminant analysis (LDA) based face recognition techniques, image representation and recognition is statistically dependent on the evaluation of the between and within matrices. This leads to the following benefits; the proposed 2D-FPCA yields greater recognition accuracy while reduces the overall computational complexity. Finally, the effectiveness of the proposed algorithm is verified using the ORL database as a benchmark. The new algorithm achieves a recognition rate of 95.50% compared to the recognition rate of 90.00% for the Fisherface method |

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.
