| Abstract | Image denoising has been an active research topic in the past decades for its broad real-world applications, but surprisingly little work has been dedicated to the quality assessment of de-noised images. In this work, we first build a database that contains noisy images at different noise levels and denoised images created by both classical and state-of-the-art denoising algorithms. We then carry out a subjective experiment using a multi-stimulus ranking approach to evaluate and compare the quality of the denoised images. Data analysis shows that there are both considerable agreement and significant variations between human subjects on their opinions of denoised images. Our results also show that state-of-the-art objective image quality models only moderately correlate with subjective opinions, and further investigations that involve both structural fidelity and naturalness measures are desirable in future development of advanced objective models. |

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.
