Abstract | This article proposes an improved H.264 adaptive intra error concealment algorithm, which enables relatively good smoothness for reconstructed image and effectively restores edge information at the same time. This algorithm adaptation chooses spatial pixel average and edge-detection-based error concealment algorithm, improves the traditional edge detection algorithm, and proposes directional weighted algorithm based on adjacent edge information. By such means as area selection, luminance signal interpolation and block position detection, the computation of decoder is effectively decreased and the difficulty in engineering application is solved. Two schemes are designed at H.264 standard test platform JM86 and verified. The result indicates that this algorithm is simple and practical, suitable for real-time processing. The peak signal to noise ratio (PSNR) is 3dB higher than that with traditional method. The subjective and objective quality of reconstructed image is improved and so the application value is pretty high. |

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.
