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.

摘要： A degraded-image restoration method includes inputting a degraded image degraded by a predetermined degradation process; reading from a storage unit a filter coefficient in a filtering process of restoring the degraded image, in which an iteration formula for minimizing a square error between the degraded image and an image obtained by degrading a restored image by the degradation process is expanded corresponding to a predetermined number of iterations; and performing the filtering process using the filter coefficient with respect to the degraded image to obtain a restored image of the degraded image. Accordingly, a throughput in an apparatus that restores the degraded image can be reduced, thereby obtaining a preferable restored image.
