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 spatiotemporal
change detection framework. Bothmethods 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.
