海上油膜及浒苔的遥感提取
Offshore Oil Film and Enteromorpha Extraction by Remote Sensing Data
摘要
Abstract
[Objective]In order to provide technical support for marine pollutant removal,the oil film and enteromorpha extract methods were explored by Quad-polarization Radarsat-2 data.[Methods]Average threshold value method-the normalized radar cross section (NRCS) are calculated (d)after using image segmentation.The resampling 10*10 average value di-vided by d was noted for t.According to t value selected a minimum threshold for oil film or enteromorpha,so that the method immediately identified the area of oil film or enteromorpha (suspension and floating)area.[Results]The method used to extract in the oil film is better than that of entropy.Extraction of suspension and floating enteromorpha by entropy and the average Angle of alpha (alpha)method are consistent with that by average threshold value method.[Conclusion]The method is effective for oil film and sea enteromorpha extract.关键词
