| Abstract | In this paper, a novel method is presented for low-latency online action recognition from skeleton data. The introduction of pose based features has reduced viewpoint and anthropometric variations, so differing execution rates and personal styles are the major sources of classification error. Previous work for online action recognition fails to adequately address both execution rate and personal style. To overcome these limitations a compression and fusion of offline action recognition approaches has transpired. Specifically, clustered action manifolds are proposed for low computational latency and template fragment matching with peak key poses are introduced for low observational latency. The style invariance of spatio-temporal manifolds is combined with the execution rate invariance of Dynamic Time Warping (DTW). Experimental results on two publicly available datasets demonstrate the high accuracy of the proposed method. |

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.
