Abstract
A method for providing enhanced subpixel resolution includes obtaining point spread function (PSF) data associated with an input image. The method also includes determining subpixel PSF data from the PSF data. The method further includes generating a filled subpixel sparse image from pixels of the input image. In addition, the method includes applying nearest neighbor pixel deconvolution (NNPD) to the subpixel PSF data and the filled subpixel sparse image to generate an enhanced subpixel image having an increased resolution.

A method for providing enhanced subpixel resolution, the method comprising:
- obtaining point spread function (PSF) data associated with an input image;
- determining subpixel PSF data from the PSF data;
- generating a filled subpixel sparse image from pixels of the input image;
- and
- applying nearest neighbor pixel deconvolution (NNPD) to the subpixel PSF data and the filled subpixel sparse image to generate an enhanced subpixel image having an increased resolution.
A system for providing enhanced subpixel resolution, the system comprising:
- an imaging system configured to capture an input image, the input image associated with point spread function (PSF) data;
- and
- at least one processing device configured to:
- obtain the input image and the PSF data;
- determine subpixel PSF data from the PSF data;
- generate a filled subpixel sparse image from pixels of the input image;
- and
- apply nearest neighbor pixel deconvolution (NNPD) to the subpixel PSF data and the filled subpixel sparse image to generate an enhanced subpixel image having an increased resolution.
A non-transitory machine readable medium containing instructions that when executed cause at least one processor to:
- obtain point spread function (PSF) data associated with an input image;
- determine subpixel PSF data from the PSF data;
- generate a filled subpixel sparse image from pixels of the input image;
- and
- apply nearest neighbor pixel deconvolution (NNPD) to the subpixel PSF data and the filled subpixel sparse image to generate an enhanced subpixel image having an increased resolution.
