Method and system for fast n-dimensional dynamic registration
First Claim
1. A method of updating the registration of a pair of images comprising the steps of:
- providing a pair of images with a source image and a first target image, and a first full registration between said source image and said target image, wherein each said image comprises a plurality of intensities corresponding to a domain of points in a D-dimensional space;
determining a second full registration between said source image and said first target image;
obtaining a second target image;
determining a registration between said first target image and said second target image; and
determining an incremental registration between said second target image and said source image, based on the registration between said second target image and said first target image and on said first full registration between said first target image and said source image, wherein the step of determining the second full registration between said source image and said first target image is performed in parallel with the steps of obtaining a second target image, determining a registration between said first target image and said second target image, and determining an incremental registration between said second target image and said source image.

Abstract
A method of updating the registration of a pair of images comprising the steps of providing a pair of images with a source image and a target image, determining a full registration between the source image and the target image, obtaining a first new target image, determining a registration between the target image and the first new target image, and determining an incremental registration between the first new target image and the source image, based on the registration between the first new target image and the target image and on the full registration between the source image and the target image. The determination of the full registration between the source image and the target image can be performed in parallel with the determination of the incremental registration between the first new target image and the source image.

13. A program storage device readable by a computer, tangibly embodying a program of instructions executable by the computer to perform the method steps for updating the registration of a pair of images, said method comprising the steps of:
-
providing a pair of images with a source image and a first target image, and a first full registration between said source image and said target image, wherein each said image comprises a plurality of intensities corresponding to a domain of points in a D-dimensional space;
determining a second full registration between said source image and said first target image;
obtaining a second target image;
determining a registration between said first target image and said second target image; and
determining an incremental registration between said second target image and said source image, based on the registration between said second target image and said first target image and on said first full registration between said first target image and said source image, wherein the step of determining the second full registration between said source image and said first target image is performed in parallel with the steps of obtaining a second target image, determining a registration between said first target image and said second target image, and determining an incremental registration between said second target image and said source image. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method of registering a pair of time-varying images, said method comprising the steps of:
-
obtaining a source image and a target image, wherein each said image comprises a plurality of intensities corresponding to a domain of points in a D-dimensional space;
initializing a full registration between said source image and said target image;
obtaining a new target image;
determining a registration between said target image and said new target image;
determining an incremental registration between said new target image and said source image, based on the registration between said new target image and said target image and on said initial full registration between said source image and said target image;
determining a full registration between said source image and said target image, wherein the steps of obtaining a new target image, determining a registration between said target image and said new target image, and determining an incremental registration are repeated until said full registration between said source image and said target image is completed; and
using said full registration between said source image and said target image to correct the incremental registration between said new target image and said source image.
