The Removal of False Detections from Foreground Regions Extracted Using Adaptive Background Modelling for a Visual Surveillance System

Abstract

Abstract. For recent surveillance systems, the false detection removal process is an important step which succeeds the extraction of foreground regions and precedes the classification of object silhouettes. This paper describes the false object removal process when applied to the 'SmartMonitor' system -i.e. an innovative monitoring system based on video content analysis that is currently being developed to ensure the safety of people and assets within small areas. This paper firstly briefly describes the basic characteristics and advantages of the system. A description of the methods used for background modelling and foreground extraction is also given. The paper then goes on to explain the artefacts removal process using various background models. Finally the paper presents some experimental results alongside a concise explanation of them.

Application of foreground object patterns analysis for event detection in an innovative video surveillance system

“…4 Sample frames presenting the simulation of a crime scene (scenario C) [7] Fig . 5 General scheme of applied background subtraction process [13] H component of HSV colour scheme, which corresponds more closely to human perception. It was experimentally found that shadow darkens the region while the hue does not vary too much [16].…”

“…Since there are various types of false detections, the usage of only one foreground image decreases the possibility of distinguishing false objects from actual OOIs. Therefore, as already mentioned, the combination of two background models, namely intensity and chrominance (hue) models, was selected for the false detection removal process and investigated in [13].…”

“SmartMonitor”— An Intelligent Security System for the Protection of Individuals and Small Properties with the Possibility of Home Automation

“…It can be utilized both inside and outside the building to increase security in houses, private apartments, nursing homes, small businesses or shops, as well as in backyards, gardens, parking spaces, building surroundings, especially near entrances or windows. “SmartMonitor” has already been described in literature [1–4]. …”
