During the data association,a kind of track before detection scheme is practiced based on the local contrast maximum likelihood of the targets.

In order to detect the point targets in the case of occlusion with cloud,following the track before detection framework,this paper presents an information association method based on grey and contrast.

Based on developing of vision recognition system of Micro-Robot World Cup Soccer Tournament, this dissertation is devoted to investigating some related techniques in computer vision, which include edge detection and contour tracking, conventional calibration techniques, self-calibration techniques, implicit calibration based on artificial neural networks.

Aiming at the complex question of edge tracing,this paper presents a new system parallel mode with parallel data and parallel processing.
