abstract = "A challenge for the use of medium spatial resolution imagery for
change detection consists of the reduced availability of ground
reference data for previous dates. We compared the accuracy of
invariant area sets, generated by three methods (Iteratively
Reweighted Multivariate Alteration Detection, Change Vector
Analysis and Spectral Gradient Difference) for two periods
(2017-2011 and 2011-2006). The classification of the Landsat-5 TM
image of 2006 was performed using as training data the sets of
points indicated as invariant in the binary maps resulted from the
three methods. Overall accuracy for seven land-use classes was
greater (80,5% and 80,2%) when using training areas achieved by
CVA and SGD, respectively than IR-MAD (76%). Were obtained
accuracies greater than 80% for the forest class. The results
stress that the combination of the IRMAD and SGD is preferable
since the CVA is more time consuming due to the subjective
application of thresholds.",
