Focusing on the problem that the detection accuracy of traffic detection system is sensitive to the changes of complex environments, this paper presents an improved method of vehicle detection. It builds and updates the background adaptively. Additionally, to improve the computation efficiency of shadow elimination, a fast algorithm of neighbor mean based on HSV model is proposed. As the occlusion...
In this paper, we propose a method of measuring the orientation of observed objects as a parametric model. The orientation is represented as angle of observed objects. We suppose that optical flow obtained from image have component of not only component of translational velocity but also revolution, scaling, and orientation. To estimate these components, it is necessary to construct nonlinear simultaneous...
The low visibility condition of underwater environments is often a limiting factor in the exploration of rivers or coastal areas. In such situations, relatively high resolution images produced by an acoustic camera can be an informative measure for the detection of terrain and objects. In this paper, we present a non-iterative super-resolution algorithm for the construction of a high resolution image...
