| Abstract | In this paper, a new online vision-based road-type classification method is proposed. The method uses video captured by a single video camera and takes into account the visual information of the whole scene by segmenting the video frames into temporally consistent frame segments. To this end, we use a video segmentation algorithm based on evolving Gaussian mixture models (GMMs). Our method consists of two stages. In the first stage, we build a priori statistical models of different road types, one model per road type under consideration. For this purpose, we use GMMs produced by the video segmentation algorithm applied to the training video data offline. In the second stage, new video frames are segmented and classified into one of several possible road types on the basis of the Bhattacharyya distance between the Gaussians produced from the new video frame and the Gaussians from the a priori models representing the different road types. Experimental results on real-world data indicate that our method outperforms the state of the art method in this area in both classification accuracy per road type and overall classification accuracy. |

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.
