| Abstract | In this paper, efficient model estimation based on particle filter for visual object tracking in automated video surveillance is proposed. Particle filter is used for our object prediction. We try to reduce complexity of particle filter by embedding non-stationary Gaussian object model into particle filter algorithm in that the dimension of the object state can be reduced. The object model is based on adaptive bounding box feature that can be used to handle non-rigid object tracking. The bounding box feature is defined as follows: image coordinate (x, y), recursive width (w) and recursive height (h). The recursive width and height will be updated by using non-stationary Gaussian formula. We use the recursive width and height as the fixed value for a set of the samples in the particle filter process. This can reduce the number of the samples improving complexity of the particle filter process. The proposed particle filter is compared with color-based particle filter to validate the proposed object model. From the experimental results, we can get the better accuracy while the number of the samples is maintained. |

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.
