Abstract:

A segmentation and recognition algorithm based on the improved OSTU method and region growing is proposed for the fire cannons jet trajectory image.First,the method of OSTU is improved to obtain the optimal segmentation threshold of jet trajectorys difference image quickly.Then,the possible target areas are segmented by the region growing method.On the basis of indepth research on and analysis of jet trajectorys shape features,the real jet trajectory is identified from the possible target areas.The experimental results show that in the case of different lighting conditions and complex backgrounds,the method presented in this paper can eliminate the interference and identify the target accurately with a high processing speed.
