摘要
通过对港口水域自动检测问题的深入研究,提出一种基于熵的感兴趣区域自动提取算法。将水域和陆地背景分离,并对分割后的二值图像进行标记,最后提取出水域。
Through the research of algorithms of automatic detecting water area in harbor,this paper presents a method which detects the interested area basing entropy.Firstly water area and land are divided,then the black-white image which has been segmented is marked and the biggest black block is considered as the water area.
