20120288212, Nov 15, 2012

Filed:

Mar 18, 2010

Appl. No.:

12/726651

Inventors:

William W. Arrasmith - Melbourne FL, US

Assignee:

FLORIDA INSTITUTE OF TECHNOLOGY - Melbourne FL

International Classification:

G06K 9/40

US Classification:

382260

Abstract:

An imaging method providing atmospheric turbulence compensation includes capturing a subject image pair. Data corresponding to the captured subject image pair is loaded into memory associated with a parallel processing device. A 2-D Fast Fourier Transform is performed on the stored image data and the transformed image data is stored. An optical transfer function is developed for the transformed image data. The optical transfer function is inverted and applied to the transformed image data to generate corrected image spectrum data that is compensated for atmospheric aberrations. An Inverse Fast Fourier Transform is applied to the corrected image spectrum data to produce corrected image data. The corrected image data is stored.

Abstract:

Imaging methods and systems providing wavelength diversity compensation to images distorted by turbulence includes capturing a subject image set in a single image frame, with the images in the set being captured at diverse wavelengths. The compensation includes using an error metric insensitive to variation in object brightness between a region of interest of an image and a corresponding region of interest in a second image in the set that is at a diverse wavelength.
