Recognizing human violent action using drone surveillance within real-time proximity.

Nowadays, the world is witnessing a significant rise in the cases of both reported and unnoticed violations. As an answer to this rising menace, video surveillance can fill the gap of covering untapped actions which lead to violence, while also ensuring a secure life. In our everyday life, surveillance can be accomplished efficiently by activity classification from drone videos. The prominent fields that have employed this technology are police work, video categorization, biometrics, and human–computer interaction. So far, no public dataset is available for violent activity classification using drone surveillance. Hence, this work aims to look into the domain of machine-driven recognition and classification of human actions from drone videos. In this study, the dataset is created using drones from different heights for an unconstrained environment. The study begins by performing key-point extraction and generate 2D skeletons for the persons in the frame. These extracted key points are given as features in the classification module to recognize the actions. The classification models used in the proposed method are SVM (support vector machine) and Random Forest. Experimental results show that the SVM model with RBF (radial basis function) kernel for activity classification is more efficient when compared to the prior proposed approaches and other experimented models. The research work has also analyzed the run time performance of the proposed system and achieve its real-time performance. [ABSTRACT FROM AUTHOR]
