Paper Abstract

The spectral dependence between neighboring pixels in the remotely sensed image is useful for the discrimination of land use/cover types, but it is neglected in most classical classification algorithms. Variogram-based method is popular in exploiting the spatial information of spectrum in the remotely sensed images. Although this method has been utilized in many ways, it still tends to misclassify the pixels near boundaries in practice and therefore leads to boundary-blurring problem. A weighted semivariogram (WSV) method is proposed to solve that problem in this paper, and the results also show good performance in improving the boundary classification accuracy of remotely sensed images.
