Fig. 2


Illustration of the feature-matching method using a coarse-to-fine strategy. The calculated displacement at a higher (larger) scale is used to constrain the determination of the feature displacements at a lower (smaller) scale. In this particular example, the displacement of the SSP at scale j + 1 is used as initial guess for displacements of its child SSPs at scale j. The initial guesses are subsequently refined by cross correlation.
