Comparison of feature extraction methods within a spatio-temporal land cover change detection framework

Abstract

In this paper, a change detection accuracy comparison is made between a recently proposed EKF method and a sliding window. Fast Fourier Transform(FFT) alternative within a spatio-temporal change detection framework. Both methods produce a mean and amplitude parameter sequence which is then used to determine a change metric which yield a change of nochange decision after thresholding. The objective is to determine which of these methods produces a change metric value that is able to best discriminate between change and no-change.
