Abstract: System and method for image turbulence correction includes: receiving a plurality of consecutive image frames; demosaicing previous, current and preceding image frames into a plurality of same size overlapping video tiles; determining a displacement of each of the video tiles; converting the video tiles of the current image frame, the previous image frame, and the plurality of preceding image frames into a frequency domain; iteratively processing the video tiles of the previous image frame, the current image frame and the plurality of preceding image frames for turbulence correction in the frequency domain; converting the turbulence corrected video tiles into a spatial domain, wherein the converted turbulence corrected video tiles form a single video frame tile including turbulence degradation correction; and mosaicing the single video frame tiles including turbulence degradation correction together to generate a full field of view turbulence correct video stream.

Abstract: A system, and method of operating the same detects moving targets in images and performs image turbulence correction. The system includes an automatic target recognizer (ATR) system including a database. The ATR includes a feature extractor and processor arranged to detect a plurality of reference features associated with targets within image frames, and calculate a position of the plurality of reference features. The system includes an image processor arranged to receive the position, demosaic the image frames into a plurality of video tiles, iteratively process the video tiles for turbulence correction to generate turbulence corrected video tiles associated with acquired targets; convert the turbulence corrected video tiles into a single video frame tile including turbulence degradation correction; and mosaic each of the single video frame tiles to generate a full field of view turbulence corrected video stream.
