| Abstract | In recent years, movement related cortical potentials (MRCP), a type of slow cortical potentials, have been used for motor intention detection for triggering external devices in close loop rehabilitation paradigm. One of the main issues with these slow frequency MRCP signals is to separate them from the background brain activity or their poor signal to noise ratio. For this reason, different filter bank for denoising are reported in the literature. In this paper, we use a signal adaptive, time-frequency based empirical method known as empirical mode decomposition to decompose the MRCP signal into its constituent frequency components called intrinsic mode function (IMF). By doing so, we can separate the slow frequency MRCP signal occupying the last few IMFs, from the high frequency noise present in the first few IMFs. By removing the first few IMFs, we obtain a cleaned MRCP signal that can be used for the detection of movement intention with much higher accuracies and less latency. Template matching approach of matched filters was used to detect the presence of signal and the results show that four different types of movement intentions can be detected using this denoising approach with an average latency of 0.70 s±0.1 before the actual movement onset. These results are much better than average latency of 0.07 s ± 0.1 reported previously in the literature on the same dataset. |

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.
