Abstract | For content-based image retrieval techniques, systems adopt certain metric to measure the similarity between images using some visual features. In most of existing approaches, the measurements are fixed up and calculated based on the whole image. The usefulness of those systems is limited because 1. The end-users are not involved in the retrieval processes. 2. The spatial information is not taken into account and end users can not put different emphasizes on different regions in the image when retrieve. Therefore, the systems demonstrate a disability to use the locally spatial relevance feedback. This paper describes an approach towards those problems to improve the discrimination power using locally spatial information. Images are divided into 5 overlapped regions and 5 neural networks are employed to measure the similarity between corresponding regions in a query image and images in the database. The relevance feedbacks for different regions from end users are used to refine the neural networks for adjusting the measurements. Results demonstrate a good potential of the methodology. |

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.
