Abstract
A method for registration of first and second images out of registration. The method includes the steps of: (a) making the edges in the first and second images more prominent; (b) thresholding the first and second images from the previous step using a threshold for which N percent of the pixels of each of the first and second images are over the threshold; (c) reducing the resolution of the first and second images from the previous step; and (d) registering the first and second images of reduced resolution from the previous step.

A method for registration of first and second images out of registration, the method comprising the steps of:
- (a) making the edges in the first and second images more prominent;
- (b) thresholding the first and second images from the previous step using a threshold for which N percent of the pixels of each of the first and second images are over the threshold;
- (c) reducing the resolution of the first and second images from the previous step;
- and
- (d) registering the first and second images of reduced resolution from the previous step.
A program storage device readable by machine, tangibly embodying a program of instructions executable by machine to perform method steps for registration of first and second images out of registration, the method comprising the steps of:
- (a) making the edges in the first and second images more prominent;
- (b) thresholding the first and second images from the previous step using a threshold for which N percent of the pixels of each of the first and second images are over the threshold;
- (c) reducing the resolution of the first and second images from the previous step;
- and
- (d) registering the first and second images of reduced resolution from the previous step.
A computer program product embodied in a computer-readable medium for implementing registration of first and second images out of registration, the computer program product comprising:
- (a) computer readable code means for making the edges in the first and second images more prominent;
- (b) computer readable code means for thresholding the first and second images from the previous step using a threshold for which N percent of the pixels of each of the first and second images are over the threshold;
- (c) computer readable code means for reducing the resolution of the first and second images from the previous step;
- and
- (d) computer readable code means for registering the first and second images of reduced resolution from the previous step.
