| Abstract | While there are ever growing focuses on mobile visual search in recent years, a comprehensive benchmark database with rich context information (such as GPS) for fair evaluation among different strategies is still missing. This paper introduces a PKUBench benchmark for the quantitative evaluations of mobile visual search with the support of GPS. It contains 13,179 images organized into 198 distinct landmark locations within the Peking University campus. Each location is captured with multiple shot sizes and viewing angles, using both digital cameras and phone cameras, each photo being tagged with rich contextual information in the mobile scenario. Moreover, this benchmark studies typical quality degeneration scenarios in mobile photographing, including variable resolutions, blurring, lighting changes, occlusions, as well as various viewing angles. Together with this benchmark, we provide the bag-of-visual-words search baselines involving contextual information refinement. Finally, distrac-tor images are further introduced to evaluate the robustness of visual search methods in this database. |

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.
