| Abstract | Super-Resolution (SR) is a set of techniques which objective is to increase and improve the resolution of an image or a video sequence. In this scope, one of the most used techniques is “fusion”, where High-Resolution (HR) images are constructed from several observed Low-Resolution (LR) images. In this paper, a fusion SR algorithm is enhanced introducing an intelligent selective filter which decides the best LR frames to be used in the process. Additionally, an adaptive Macro-Block (MB) size decision maker has been developed to specify an appropriate frame division into MBs. This not only improves the quality but also reduces the computational cost of the baseline algorithm, avoiding the incorporation of non-correlated data. It is also presented how this new algorithm performs well with typical SR applications, such as underwater imagery, surveillance video or remote sensing. The algorithm results are provided on a test environment to objectively compare the quality enhancement of images processed by bilinear interpolation and the two aforementioned methods: Baseline and Enhanced SR, presenting a quantitative comparison based on the PSNR (Peak Signal-to-Noise Ratio) and the SSIM (Structural SIMilarity index). |

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.
