| Abstract | For the purpose of automatic video quality evaluation, Peak Signal-to-Noise Ratio (PSNR) has been the most wellknown full reference quality metric since a long time. Improving on PSNR, several other pixel-based quality metrics have been developed, namely Structural SIMilarity (SSIM), Multi Scale-SSIM (MS-SSIM), and Video Quality Metric (VQM). The goal of these objective video quality metrics is to replace time-consuming and expensive subjective quality assessment experiments. These alternative objective metrics have already been evaluated on several video compression schemes, such as MPEG-2 and H.264/AVC, transported over different kinds of network protocols and under a large variation of network characteristics. In January 2013, the successor of the Advanced Video Coding (H.264/AVC) standard, named High Efficiency Video Coding (HEVC), has been finalized. Although HEVC is still a block based hybrid video compression standard, some radical changes are made to subjectively improve the compression efficiency compared to H.264/AVC. Until now, the alternative quality metrics have never been evaluated on this new compression scheme. Therefore, in this paper, we analyze the difference in performance of these full reference metrics. Based on subjective evaluations, a performance analysis is presented which shows the validity of these models when applied to HEVC compressed video content. |

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.
