摘要： An image matching apparatus includes a numerical analyzing unit that solves an equation of motion numerically. The equation of motion is formulated as an image matching state transition model representing a mapping relation between a source image and a destination image. The equation of motion represents a force applied on each lattice point of the destination image including potential energy force. The numerical analyzing unit calculates the potential energy force, and sets a convergence value of a solution of the equation of motion as a mapping relation between the lattice point of the source image and the lattice point of the destination image based on the numerical analysis.
