Extraction of parameters from a wavelet packet analysis for terrain matching
Bogdan E. Popescu, P. Costa, P. Larzabal, H. Clergoet · 2002
A new method for terrain matching is proposed, by modeling the sea bed surface as a nonstationary process with stationary increments. The stationarizing properties of a 2D separable wavelet packet decomposition are applied for deriving discriminant parameters. We also propose a method to match maps with different orientations, using a two stage position estimation algorithm.
