Paper Abstract

Laser underwater target image acquired by using synchronization-scanning imaging technology is always disturbed by strong laser beam. Correlation analysis algorithm based on texture-driven cannot detect target in these images at first hand. In these laser images energy of mighty laser beam is converged in a certain direction, on the contrary distribution of weak target energy is symmetrical in all directions. Some certain multi-scale and multi-channel Gabor filters can boost up some certain direction energy and at the same time decrease other certain direction energy. Therefore, the mighty laser beam with single certain direction in the image is restrained by appropriate Gabor filters. In order to gain the better result, firstly small size Gabor filters with four directions are used to process the laser target image, then scale size of Gabor filter is increased step by step until result image processed by Gabor filters is approving. After that texture-driven correlation analysis algorithm is processed on the image filtered by Gabor filters with appropriate size and direction and then weak target is detected. Experiments prove that the proposed algorithm based on Gabor filter can efficiently eliminate interference of mighty laser beam and detect laser underwater image target effectively.
