| Abstract | Today, many security applications rely on imaging sensors. However, the quality of the captured image is highly susceptible to environmental lighting conditions such as poor or non-uniform illumination. Security imaging systems rely on efficient real-time image enhancement. For autonomous systems, determining and producing the best visually enhanced image output as perceived by the human visual system remains a challenge. In this paper, we present a metric for autonomous evaluation that will enable security systems to automatically determine the best human visual quality image. To achieve this, we have established a “no parameter no reference” metric that can determine the best visually pleasing image. The metric is algorithm independent such that it can be utilized for a diversity of enhancement algorithms. We present our DCT transform domain measure of enhancement (TDME). Unlike spatial domain measure of enhancement methods, the proposed measure is independent of image attributes and does not require any parameter selections to operate. The proposed measure is applicable to compressed and non-compressed images and can be used as an enhancement metric in conjunction with many different image enhancement methods. |

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.
