“…For tracking in a VSN, the detection can be done by object segmentation from the camera scenes. Background subtraction [28][29][30] is an important approach for object segmentation in visual surveillance system, which compares two images to acquire the difference. A simple illustration of background subtraction is shown in Figure 4.…”

Target tracking is one of the important applications of wireless sensor networks. For a visual sensor network, the visual sensors have particular characteristics such as directional sensing, limited angle of view, and line-of-sight view. Target tracking with visual sensors is different from that with scalar sensors. Moreover, the quality of sensed visual data can be much important in many applications. In this paper, the concept of Voronoi diagram is utilized for target tracking in visual sensor networks. The structure of Voronoi cells is suitable for the design of a distributed/localized algorithm and it exists a property of bisector for dividing a distance line or region. This paper proposed a Voronoi-based distributed sensor handover protocol for visual sensor networks. The simulation result shows the benefits of our proposed approach in terms of target-detected latency, target-tracked ratio, and average target distance, which indicates that the quality of target tracking service can be improved with the proposed approach for visual sensor networks.

“…Anandhalli and Baligar (2015) proposed an improvised background subtraction model for real-time tracking that solves the problems of shadow detection. Alvar et al (2014) proposed an efficient model for background subtraction that processes only some pixels of each image. This model could result in a significant reduction in computation time for subsequent image analysis.…”

The moving object detection and tracking technology has been widely deployed in visual surveillance for security, which is, however, an extremely challenge to achieve real-time performance owing to environmental noise, background complexity and illumination variation. This paper proposes a novel data fusion approach to attack this problem, which combines an entropy-based Canny (EC) operator with the local and global optical flow (LGOF) method, namely EC-LGOF. Its operation contains four steps. The EC operator firstly computes the contour of moving objects in a video sequence, and the LGOF method then establishes the motion vector field. Thirdly, the minimum error threshold selection (METS) method is employed to distinguish the moving object from the background. Finally, edge information fuses temporal information concerning the optic flow to label the moving objects. Experiments are conducted and the results are given to show the feasibility and effectiveness of the proposed method.
