| Abstract | This paper describes an improved motion adaptive deinterlacing method which uses five consecutive fields for motion detection. The motion detection algorithm, searches for motion activity between the fields by a hierarchical block based structure so it reduces the computation amount considerably. This reduction depends on the level of motion activity between the fields and could be of the order of two for slow motion scenes. The motion detection algorithm applies the same motion detection structure to all three color components of the video sequence and the motion detection results of different colors are then compared to obtain more reliable motion detection results. Searching between five fields and also using color data in motion detection makes the motion detection step more accurate and robust to noise and consequently it improves the overall performance of the deinterlacing algorithm. Missing lines of interlaced video are then interpolated using the motion activity data of the interlaced video fields; by giving more weight to temporal (or interfield) interpolation in static parts of the video scene and more weight to spatial (or intrafield) interpolation in dynamic parts of the video scene. Experimental results show that the proposed deinterlacing method gives less interpolation errors than most available deinterlacing 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.
