海上可见光图像清晰化处理及显示方法

Clear Processing and Display Method of Sea-Visible-Light Image

通过对海空背景图像基本特征、图像高频增强算法、海上图像去雾交互算法及改进的色调映射算法的分析和研究,提出了一种基于图像滤波、图像增强及图像复原的融合式的图像清晰化处理及显示方法,并据此设计了图像清晰化处理显示软件系统。实验结果表明:该方法可显著改善海上可见光图像的显示效果,并具有较好的实时性。

In this paper, the characteristic of sea-visible-light image under the sea-sky background, the high frequen cy image enhancement and the interactive defogging method are analyzed. Then a new method of enhancement and clearer display of sea-visible-light image is presented based on methods of image filtering, image enhancement, and image restoration. Meanwhile, a display system based on the method is developed. The experiment results shows that the system improves the image quality obviously with a good real-time performance.
