Paper Abstract

There are two kinds of image in the field of imaging for the underwater target due to using two types of light source, respectively, continue green-blue laser and pulse green-blue laser. When pulse laser is used, the obtained image has the characteristic of low contrast, small dimension of target and complex background. The method of multiple correlation peak-value detection, which is based on the correlativity of pixels in the region of target, can be directly used to implement target detection for the underwater laser image. When continue laser is used in the process of imaging for the underwater target, there is a beam of strong light in the image, which makes it difficult to implement target detection. Therefore, we use the multi-scale and multi-channel Gabor filter group with the character of direction selection to depress the disturbance of the strong beam firstly, and then, use the multiple correlation analysis method to detect the weak target in the image. Experimental results show that these methods are practical and effective.
