| Abstract | A low complexity but effective method in image and video detail enhancement – in-place similarity is proposed. In-place similarity is the statistic result of different kinds of nature image patches when similarity measurement is done in super resolution research, finding that patches in the upscale image have a good match around its original location in the corresponding lower ones. On the basis of the in-place similarity, a simple assumption is made that detail layer is the high-frequency component of twice search and patch match result. Then, images under the framework of super resolution techniques are enhanced. Unlike many current algorithms that need to adjust parameters for different images to acquire best outputs the approach mentioned here is adaptive. Moreover, many algorithms have outcome with intensity and contrast change, the algorithm proposed here can prevent images from over enhancement with obvious nature looking effect. Extensive experiments demonstrate that the algorithm mentioned here is simple with robust good performance both subjectively and objectively. It is particularly useful for practical applications and easily hardware implemented in FPGA, where input images require diverse detail textures. |

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.
