Abstract | Regarding safety and security, felonies and crimes with physical violence remain a significant problem worldwide. Some solutions for pedestrian safety are guards, police car patrolling, sensors, and security cameras. Nonetheless, these methods react only when the crime takes place. In the worst cases, the damage may be irreversible when it has already occurred. Therefore, numerous methods based on Artificial Intelligence have been proposed to solve this problem. Many approaches to detect violent behavior and action recognition rely on 3D convolutional neural networks (3D-CNNs), spatio-temporal models, long short-term memory networks, pose estimation, among other implementations. However, these approaches work in a limited fashion and have not been adapted to uncontrolled environments. Thus, a significant contribution from this work is the development of an innovative solution model capable of detecting violent behavior. This approach focuses on pedestrian detection, tracking, pose estimation, and neural networks to predict pedestrian behavior in video frames. Our proposal uses a time window frame to extract joint angles, given by the pose estimation algorithm, as features for classifying behavior. Another significant contribution of this work is the creation of a new database, Kranok-NV, with a total of 3,683 normal and violent videos. This database was used to train and test the solution model. For the evaluation, we designed a protocol using 10-fold cross-validation. We obtained an accuracy slightly above 98% on the Kranok-NV database with the implemented solution model. Although the proposed solution model detects violent and normal behavior, it can be easily extended to classify other types of behavior. |

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.
