Abstract

This article compares four different alternative image representations in the context of a structure-based change detection. The framework is taken from the already published Curvelet-based change detection approach. Only the transform step is modified by inserting three additional transforms: the Laplacian pyramid, the Wavelet and the Surfacelet transform. The results of the change detection are compared to the single pixel difference image in order to find the representation that best illustrates the underlying structures. The Curvelet transform again turns out to be very powerful in describing man-made objects and landscapes.
