Human's safety in construction areas is vital. A hard hat is required to enter a construction area. Stopping a person who is not wearing a hard hat entering a construction area is very important. Video-based surveillance to detect hard hat is a new solution to this safety problem. This paper brings different video processing techniques together to construct a framework for fast and robust hard hat...
This paper presents an adaptive empirical algorithm which identifies static shadows within video sequences and produces static shadow maps that are used to improve the performance of video based automatic incident detection (AID) systems. The algorithm distinguishes between static shadows and other objects using background generation, motion detection, and three static shadow filters. The proposed...
