Distributed camera networks have been deployed in the modern surveillance systems. The camera link model, including transition time distribution and brightness transfer function that represent the space-time relationship and color model between two cameras, is a critical element for tracking objects across the cameras. In this paper, we formulate the estimation of the camera link model as an optimization...
Conventional surveillance systems usually use multiple screens to display acquired video streams and may cause trouble to keep track of targets due to the lack of spatial relationship among the screens. This paper presents an effective and efficient surveillance system that can integrate multiple video contents into one single comprehensive view. To visualize the monitored area, the proposed system...
This paper proposes a recognition method for light objects in a video for real-time application and the movement of the surrounding objects. The method extracts the objects by considering known geometric arrangements and blinking frequency, while the latter is also used to remove the image noise. Therefore, locations of the light objects can be found rapidly, and the on-off blinking states of these...
In this paper, we present a low-cost driving assistant system which can provide the surrounding image of a vehicle in a bird's-eye view. By implementing a fast image stitching algorithm on an embedded platform, this system can generate the around-vehicle view in real time from four fisheye cameras mounted around the vehicle. Moreover, we also propose a dynamic boundary determination method to allow...
A stereo obstacle detection method based on images symmetrical move and cell partition is presented in this paper. This algorithm gets each cell's optimum offset by calculating the minimum non-similarity of cell, and merges Cell of Interests (COIs) to calculate obstacles in the most probably obstacle regions, and gives information of these obstacles. The paper introduces the perspective projection...
