Abstract
Exemplary super-resolution methods and systems may generate, or create, a super-resolution based on a plurality of low-resolution images. Such exemplary methods and systems may utilize image registration and back-projection to provide intermediate imaging data, and then use inverse problem solving to remove any back-projection effects as well as noise to generate a super-resolution image.
Claims24
A method for generating a super-resolution image of an object of interest comprising:
- providing an initial low-resolution image of an object of interest;
- projecting the initial low-resolution image into a high-resolution grid, wherein the high-resolution grid defines a higher resolution than the initial low-resolution image;
- providing a plurality of low-resolution images of the object of interest obtained from a plurality of different positions relative to the object of interest;
- registering the plurality of low-resolution images within the high-resolution grid such that each image of the plurality of images is shifted less than one pixel away from the initial low-resolution image;
- projecting the plurality of low-resolution images into the high-resolution grid to provide an intermediate super-resolution image;
- and
- removing back-projection effects from the intermediate super-resolution image using inverse problem solving to provide a super-resolution image of the object of interest.

A system for generating a super-resolution image of an object of interest comprising:
- imaging apparatus comprising one or more imaging sensors to capture low-resolution images of an object of interest;
- and
- computing apparatus comprising one or more processors, wherein the computing apparatus is configured to:
- receive a plurality of low-resolution images of the object of interest obtained from a plurality of different positions relative to the object of interest from the imaging apparatus;
- project an initial low-resolution image the plurality of low-resolution images into a high-resolution grid, wherein the high-resolution grid defines a higher resolution than the initial low-resolution image,
- register the remainder of the plurality of low-resolution images within the high-resolution grid such that each image of the plurality of images is shifted less than one pixel away from the initial low-resolution image,
- project the remainder of the plurality of low-resolution images into the high-resolution grid to provide an intermediate super-resolution image, and
- remove back-projection effects from the intermediate super-resolution image using inverse problem solving to provide a super-resolution image of the object of interest.
