    abstract = {The next generation of warships might be virtually invisible to the human eye. These can achieve by
painting ships with meta-material. These materials can bend light around an object, making it appear to an
observer as though the waves have passed through space. We have developed a method to identify these
ships target with the help of image processing. Research on the extraction of ship target in multiple sea-sky
backgrounds has significant value to improve the capability of imaging-typed sea navigation and marine traffic
control systems. According to the imaging property of complex sea-sky background a reliable ship target
extraction method proposed in this study. The general guideline is that getting the sea-sky division line as a
priori knowledge and then the potential target area is determined by a discontinuous region of the sea-sky
division line. Firstly, a local selective window filter is adapted to filter the image; secondly, eight directions
Sobel operator edge detection method and gradient Hough transform are combined to extract sea-sky division
line in the picture then a multi-histogram matching technique is adopted to remove the sea and sky background
and thus ship target obtained from complex background. The experiments show that our method has the merits
of robustness to noise, small computational complexity and stability.}
