Patent ID: 7440619

Claim:
An image matching method for detecting a mapping from a first image to a second image, comprising: setting a first lattice having a plurality of first lattice points to a first image; setting a second lattice having a plurality of second lattice points, each second lattice point of the second lattice points of corresponding to each first lattice point of the first lattice points, to a second image; computing potential force applied to the each second lattice point by a gradient of an image correlation potential energy based on a position of the each first lattice point, pixel data of the each first lattice points, a position of the each second lattice point and pixel data of the each second lattice point; computing elasticity force applied to the each second lattice point from an elasticity energy between the each second lattice point and adjacent lattice points on the second lattice which are adjacent to the each second lattice point; computing frictional force occurring at the each second lattice point; performing a numerical analysis of an equation of motion regarding the second lattice points and based on the potential force, the elasticity force and the frictional force to obtain a convergence state of the second lattice points; and adding a new lattice point between an adjacent lattice point pair of the second lattice points according to a distance between the adjacent lattice point pair while the numerical analysis of the equation of motion is performed.
