Abstract: Human motion detection and analysis is currently an important area of research, motion analysis help us to solve many problems. An Automated Video Surveillance Model is presented in this paper. The model which I proposed is capable of detecting and monitoring people in both environments Indoor and outdoor. The Model is capable to find out the Suspicious and Non-Suspicious activities. It also detects multiple peoples in video and monitoring their activities. Moving targets are detected and their boundaries extracted, we use star skeletonization technique with the adaptive centroid point to create human skeletons. In this paper we use HMM-based methodology for action recognition.
