Intelligent Ship-Bridge Collision Avoidance ...

Faced with increasingly serious security situation in bridge area, a moving ship target detection and tracking method based on the complex background of the bridge area is presented. The background model is based on a modified Gaussian Mixture Model. The algorithm upgrades the background model in real time，Foreground area is extracted by adaptive threshold method by marking each moving region in the binary image, the geometrical features parameters such as width, height, centroid position and speed can be extracted, which lay the foundation for the analysis and track of moving.
