Object Track in Underwater Sonar Images

A method based on the particle filter was proposed to resolve the problem of target track in looking forward sonar image sequences. The theory of particle filter was illustrated, and it was used to estimate the situation of objects in sonar images. Considering the relation between the process noise and the steady results, process noise was set by the adaptive strategy. At last, the results of experiments using real scan sequences were presented, and they show that the method is robustness and effective.
