| Abstract | This study proposes a simple and fast pothole detection method of a video using spatio-temporal saliency, where a pothole is a type of failure on an asphalt pavement. In monocular vision, potholes typically have two visual properties. First, potholes have low-intensity areas that are darker than nearby pavement because of shadows. Second, the texture inside the potholes is coarser than the nearby pavement. However, these two visual properties are not sufficient for accurately detecting potholes because of shadows on the pavement and lack of the texture. In this study, the above challenges are addressed by detecting slower objects that are coming closer to a moving vehicle. Pothole is a stationary object ahead on the road. In terms of the relative speed, pothole is a slower object than a moving vehicle. In the video sequence acquired from a dash-cam, different image characteristics appear depending on the relative speed of objects such as potholes and cars ahead. The proposed method detects outliers using spatio-temporal saliency in the yt image: a slower object is represented as diagonal outliers. Experiments with several dash-cam videos show the effectiveness of the proposed method for real video sequences that contain potholes, cars, road lanes, and pavement markings. |

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.
