本文介绍应用数字图像处理技术对渤海湾西部海河口附近海域卫星遥感图像信息进行KL变换的处理结果。我们选取前三个主分量图像,从伪动态分析观点出发,对海河口近岸海域污染情况进行了数据和图像的综合分析解译。结果表明:海河口近岸海域各部分均具有不同程度的污染,污染梯度与海岸垂直,浓度由海岸向外海递减,不同等级的污染区基本呈南北向条带状分布。
This paper introduces the application of digital image processing technology to the west Bohai Bay estuary near the sea remote sensing image information KL transform results. We select the first three principal component images, from the point of view of pseudo-dynamic analysis of the coastal estuaries Haihe River estuary pollution and data analysis and interpretation of a comprehensive analysis. The results show that all parts of the coastal area of the Haihe River estuary have different degrees of pollution. The pollution gradient is vertical to the coast and the concentration decreases from the coast to the outer sea. The polluted area of different grades basically distributes in a stripe pattern of north and south.
