Remote sensing image registration approach based on a retrofitted SIFT algorithm and Lissajous-curve trajectories

Opt Express. 2010 Jan 18;18(2):513-22. doi: 10.1364/OE.18.000513.

Abstract

Through retrofitting the descriptor of a scale-invariant feature transform (SIFT) and developing a new similarity measure function based on trajectories generated from Lissajous curves, a new remote sensing image registration approach is constructed, which is more robust and accurate than prior approaches. In complex cases where the correct rate of feature matching is below 20%, the retrofitted SIFT descriptor improves the correct rate to nearly 100%. Mostly, the similarity measure function makes it possible to quantitatively analyze the temporary change of the same geographic position.
