In this article, a newsegmentation method based on traditional region growing (RG) is proposed for high resolutionremote sensing imagery. This method takes regional minima from horizontal and vertical gradient maps of the image as seeds for the following region growing processing. The new method consists of several steps as follows: (1)deriving a morphological gradient map from the input multispectral...
On the basis of combing matter-element extension method with index reflecting flood damage intensity and the degree-level analysis method, a new the comprehensive quantitative evaluation model is established for flood damage intensity. Use this model to make comprehensive quantitative evaluation of the flood in Shandong province. The result shows that not only the flood quantitative level and accuracy...
