Abstract:

Based on density sampling and dynamic time warping distance, this paper proposes a semi-supervised fuzzy cluster method to partition hyperspectral data set into several groups. The labeled samples are first obtained by density sampling method. Then the dynamic time warping distance is computed between a pair of samples. Lastly, semi-supervised fuzzy c-means is employed to cluster the hyperspectral image. To validate the proposed method, the Indian Pines and Pavia U data sets are chosen to feed our method. The experimental results show that it can discover the ideal clusters by the proposed method.

Key words: hyperspectral image, dynamic time warping distance, semi-supervised fuzzy clustering, density sampling
