Abstract
A method and system for correcting geometric deformations in an aligned image. A shape deformation correction unit is provided for receiving the aligned image and based thereon for generating a shape-corrected image. A space deformation correction unit is coupled to the shape deformation correction unit and receives the shape-corrected image. The space deformation correction unit uses the shape-corrected image to generate edges and interfaces, and further generates a corrected image based on the interfaces and the shape-corrected image.
Claims21
A method for correcting geometric deformations comprising:
- (a) receiving a aligned image having a plurality of dots that have undergone geometric deformation;
- (b) correcting the shape deformations of the dots in the aligned image by utilizing at least one morphological operation to generate a shape-corrected image;
- and
- (c) correcting the space deformation in the shape-corrected image by utilizing row/column gradient statistics to generate a corrected image.
A geometric deformation correction system comprising:
- a shape deformation correction unit for receiving a aligned image and based thereon for generating a shape-corrected image;
- and
- a space deformation correction unit, coupled to the shape deformation correction unit, for receiving the shape-corrected image, generating edges and interfaces, and generating an aligned image based on the interfaces and the shape-corrected image.
