| Abstract: | Lichi information was extracted based on support vector machines and spectral similarity scale in the paper.Support Vector Machine(SVM) is a new prospecting technique in remote sensing.But the selection of object sample is always a difficult problem.Zhongxin town in Zengcheng city is taken as a typical region.Lichi samples are extracted by the means of Spectral Similarity Scale and lichi information is further extracted by the means of SVM.We find that the lichi information is nearly in accordance with the known lichi planting areas by on the spot investigation and area estimate.The experiment shows that it is an effective lichi information extraction approach. |
