Chen and Zhang (2004) propose robust kernelized versions KFCM_S, KFCM_S1 and KFCM_S2 by applying the kernel methods. Huang et al. (2005) proposes a W-k-means algorithm that can automatically calculate variable weights. In this paper we propose W-k-means algorithms with spatial correction, and we call them AWKM_S2 and RAWKM_S2. Some numerical and image experiments are performed to assess the performance of AWKM_S2 and RAWKM_S2 in comparison with KFCM_S2.Experimental results show that the proposed AWKM_S2 and RAWKM_S2 have better performance.
