Pedestrians Tracking in a Camera Network

چکیده مقاله:

With the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. Therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. Tracking people as they move through a camera network with non-overlapping field of view is a challenging issue. It requires re-identification of objects when they leaves one field of view and appears at another scene later. The appearance of the people is changed significantly among the cameras due to illumination changes, parameters of camera, viewing angle, and deformable geometry of people. Additionally the observations of people are often broadly separated in time and space and common proximity techniques can not be used to constrain possible correspondences. In this paper a new feature was proposed to represent the appearance of people, which is capable of dealing with the common illumination changes occurring in indoor environment. To produce the proposed feature, first the image was transformed to YCbCr color space. Then diagonal vectors of color co-occurrence matrix of each individual were extracted and normalized. Experimental results from a real surveillance scene showed the efficiency of the proposed method.

Robust Descriptors Fusion for Pedestrians' Re-identification and Tracking Across a Camera Network

In this paper, we introduce a new approach to identify people in multi-camera based on AdaBoost descriptors cascade. Given the complexity of this task, we propose a new regional color feature vector based on intra and inter color histograms fusion to characterize a person in multi-camera. This descriptor is, then, integrated into an extensive comparative study with several existing color, textu...

A novel method for tracking and counting pedestrians in real-time using a single camera

This paper presents a real-time system for pedestrian tracking in sequences of grayscale images acquired by a stationary camera. The objective is to integrate this system with a traffic control application such as a pedestrian control scheme at intersections. The proposed approach can also be used to detect and track humans in front of vehicles. Furthermore, the proposed schemes can be employed...

Tracking Multiple Pedestrians in Crowd

In the domain of city design, the demand for the development of the visual tracking method is increasing, which provides the pedestrian paths. This paper proposes the tracking method which reduces the ambiguity of matching. When features of a pedestrian are ambiguous in the original image, the proposed method generates plural candidates for the pedestrian path. In the following frames the propo...

Long-term tracking of multiple interacting pedestrians using a single camera

Detection and tracking are important components of many computer vision applications including automated surveillance. Object detection should overcome challenges such as changes in object appearances, illumination, and shadows. In our system, Gaussian mixture models are used for background subtraction to detect moving objects. Tracking is challenging because measurements from the object detect...
