Real Time Detecting Algorithm for Underwater Moving Targets
水下运动目标实时检测算法研究

An algorithm of real time detecting underwater moving targets was presented against underwater complex environment.The difference image was obtained by subtraction between frames in image series based on analyzing in detail characteristic of underwater images.The appropriate threshold was selected and the binary image of the difference image was obtained.The image segmentation was completed to the binary image.A definition of linear level was given based on targets in the difference image were formed by moving.The shape of targets was characterized effectively.Therefore,real time detecting underwater moving targets was implemented.
