A Small Targets Tracking Method for Water Mine Sonar Image Array

Combining the static feature and the dynamic path in consecutive image array of small targets, this paper proposes a detecting method for small targets in sonar image: Improving the selection of (SRG) seeded region growing method, and defining the size of searching sub window, this paper realizes the selection of suspected targets in single image that have certain SRR (signal-to-reverberation ratio), to enhance the detection probability, we build the relative moving modal of vessel and targets, considering the shaking of vessel, obtain the searching limits and moving path of suspected targets in consecutive image array, and raise the principle of targets determination utilizing the IVF (intensity variation function). Experiment results show the validity of the algorithm.
