| Abstract(in English) | In this paper, we propose a method for an automatic satellite image segmentation, which utilizes data distribution patterns in multi-dimensional feature space, cloud pixels in particular. The algorithm of the proposed method mainly consists of k-means method and Competitive Hebbian Learning to preserve a topology of data in the feature space. To demonstrate a validity of the proposed method, we apply several satellite image data to the method. The result clearly shows that extraction of cloud pixels is possible with high accuracy. In addition, our proposed method identifies high and low cloud pixels, and snow pixels in satellite image data. |
