The Empirical Mode Decomposition has been used to present a new approach for denoising of regular and chaotic time series originating from the nonlinear systems. The proposed filtering approach is based on the frequency distribution of different Intrinsic Mode Functions (IMFs). It provides complete frequency and noise strength information present in the(More)
This paper presents an unsupervised change detection method for satellite images based on normalized neighborhood Gustafson Kessel Clustering. The method works in two phases in the first phase a difference image is created from the two bi temporal satellite images using normalized neighborhood ratio. The difference image is then clustered into two clusters(More)
