Classification is one of the most important procedures in high-resolution remotely sensed image information extraction. This paper introduced Adaboost-SVM algorithm to IKONOS image classification. The classification performance of Adabost-SVM and single SVM were quantitatively analyzed and qualitatively evaluated. The results show that: In the case of small training samples, Adaboost-SVM outperforms...
The paper classifies urban land cover object-oriented. First, use the Mean Shift algorithm to segment the digital aerial image of study area. By changing the algorithm initial-parameters, different scales of the segmentation results are got, and an optimal scale segmentation result is selected from these results, as the data source of the classification process. Then, by analyzing the spectral features,...
Jiangsu province, which has vast population and limited land, is facing with land resources shortage. However, the offshore radial sand banks provide huge potential land reserve resources. But, epeirogenic movement and the variation of elevation of the radial sand banks are quite frequent in coastal area of Jiangsu province; Hence, mastering law of the variation of elevation of the radial sand banks...
