Tracking multiple objects in surveillance scenarios involves considerable difficulty because of occlusions. We report a novel tracker - based on reliability tracking - that demonstrates superior performance under high degrees of occlusion. In our method, distinguishable features between the target and non-target are represented as the object's reliability. When the selected features are no longer...
This paper introduces a novel approach to background modelling. We propose using initially a method to extract scene parameters from a sequence of frames. These parameters, together with an initial background model, are used as a starting point for a background subtraction method based on fuzzy logic. Our method permits modelling the background and detecting moving objects in a video sequence without...
Night surveillance is a challenging task because of low brightness, low contrast, low signal to noise ratio (SNR) and low appearance information. Most existing models for night surveillance share the following problems: a lack of adaptability for different scenes and separation between detection and tracking. To solve these problems we propose a model based on salient contrast change (SCC) feature,...
In this paper we present a robust method for background subtraction from a fixed camera in video surveillance system. The background subtraction is an important part of object tracking and many algorithms have been proposed for decades. Mixture of Gaussian for those in this paper is very famous and used widely. We present the robust method that can adapt the background model to various situations...
This paper presents an Intelligent Surveillance System which can be used in real scenes. Our aim is to establish a reliable background from a complex one via a accurate segmentation method followed by object tracking. The system is able to continue tracking the objects regardless if the objects are overlapping or separate. The system uses the TI TMS320DM6446 Davinci development kit, inputs image sequence...
