Abstract: Nowadays it is required to design intelligent visual surveillance systems which automatically detect abandoned objects in public places to strengthen the social safety. Already recognized abandoned objects can be occluded partially or fully by surrounding people in public places after the first recognition. To improve an essential recognition performance index PAT, the system should overcome the occlusion problems. In this research, a design scheme is newly proposed to construct the robust detection system which is comprised of multiple stages considering the occlusion problem. To show the feasibilities of the proposed system, the evaluation was tried for the prepared image streams including 6 various situations and the experimental results show 96% and 75% in PAT performance for intrusion and abandoning events, respectively. Finally in spite of full occlusions by multiple persons, the proposed system shows the capability to continuously recognize the abandoned object after complex occlusions disappear.

TL;DR: This paper describes a pedestrian detection system that integrates image intensity information with motion information, and is the first to combine both sources of information in a single detector.
Robust abandoned object detection using dual foregrounds
TL;DR: A pixelwise method that employs dual foregrounds to extract temporally static image regions that indicate objects that were brought into the scene at a subsequent time, such as abandoned and removed items, illegally parked vehicles is presented.
