Abstract
A method and apparatus that improves the quality of digital images. When provided a plurality of digital images, the method and apparatus aligns the digital images to a reference coordinate system, and synthesizes an enhanced image such that the regions of image overlap between any two images have substantially improved quality.
Claims24
A method for producing an enhanced quality digital image from a plurality of source images representing a scene comprising the steps of:
- selecting one of the source images as a reference image;
- aligning image information within each source image with a reference coordinate system of said reference image;
- spatially interpolating pixels in said reference image;
- warping each of the other source images with respect to said spatially interpolated reference image to produce a plurality of warped images;
- and
- combining the image information in each of said warped images to produce an enhanced image.
Apparatus for producing an enhanced quality digital image from a plurality of source images representing a scene comprising:
- an image selector for selecting one of the source images as a reference image;
- an image alignment module for aligning image information within each source image with a reference coordinate system of said reference image;
- a pixel interpolator for spatially interpolating pixels in said reference image;
- an image warping module for warping each of the other source images with respect to said spatially interpolated reference image to produce a plurality of warped images;
- and
- an image combining module for combining the image information in each of said warped images to produce an enhanced image.
A digital storage medium containing a program that, when executed by a general purpose computer, causes the computer to perform a method for producing an enhanced quality digital image from a plurality of source images representing a scene comprising the steps of:
- selecting one of the source images as a reference image;
- aligning image information within each source image with a reference coordinate system of said reference image;
- spatially interpolating pixels in said reference image;
- warping each of the other source images with respect to said spatially interpolated reference image to produce a plurality of warped images;
- and
- combining the image information in each of said warped images to produce an enhanced image.
