US 2006/0188169 A1 · Extended range image processing for electro-optical systems

Abstract

A method and apparatus for processing imagery using images acquired via any known Electro-Optical (EO) system. In accordance with exemplary embodiments of the present invention, a first frame of data is selected as a template frame (e.g., a given frame). A second frame of data can be captured using the EO system. At least a portion of the second frame can be correlated with the template frame to generate a shift vector. The second frame can then be registered with the template frame by interpolating the second frame using the shift vector and re-sampling at least a portion of the second frame to produce a registered frame. The template frame can also be re-sampled. The registered frame and the re-sampled template frame can then be combined to generate an averaged frame. The averaged frame can be spatially filtered to enhance edges within the averaged frame.

Dependent claims

A method of enhancing visual images, comprising the steps of:

(a) selecting a first frame of image data as a template frame;
(b) capturing a second frame of image data;
(c) aligning the second frame of image data with the template frame of image data by correcting line-of-sight deviations therebetween;
(d) spatially oversampling at least a portion of the aligned second frame of image data by a factor greater than one;
(e) integrating the spatially oversampled portion of the aligned second frame of image data with image data of the template frame;
and
(f) repeating steps (b) through (e) to process subsequently-captured frames of data into a continuous video stream, wherein the first and second frames of image data are based on an input data from a stationary infrared sensor.
