| Abstract | This paper proposes a convolution particle filtering approach for extended object tracking. Convolution particle filters (CPFs) are likelihood free filters. They are based on convolution kernel probability density representation. They use kernels to approximate the likelihood of the observations and represent the likelihood when it is analytically untractable or when the observation noise it too small. Hence, the CPFs represent a sub-family of particle filters with improved efficiency in state estimation of nonlinear dynamic systems. A CPF is designed and implemented for track maintenance of an object with an elliptical shape. The object kinematics and its extent are estimated in the presence of dense clutter. This nonparametric filter is validated with a Poisson model for the measurements, originating from the target and clutter. Simulation examples illustrate the filter performance. It is shown that the CPF yields correct estimates of the joint probability density function of the state variables and unknown static parameters. The results obtained for the extended objects show that the CPFs provides accurate on-line tracking, with satisfactory estimation of the target shape and volume. |

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.
