PRE-FIGHT DETECTION - Classification of Fighting Situations using Hierarchical AdaBoost
Scott Blunsden, Robert Bob Fisher · 2009
Abstract: This paper investigates the detection and classification of fighting and pre and post fighting events when viewed from a video camera. Specifically we investigate normal, pre, post and actual fighting sequences and classify them. A hierarchical AdaBoost classifier is described and results using this approach are pre- sented. We show it is possible to classify pre-fighting situations using such an approach and demonstrate how it can be used in the general case of continuous sequences.
