Hybrid motion image compression

摘要

A system and method for processing images of a scene captured by an imaging platform include a correction processor configured to determine a plurality of coefficients associated with transformations that substantially correct expected inter-frame changes in the images caused by relative motion between the scene and the imaging platform; a transformation processor configured to transform the captured images using the plurality of coefficients and transformations so as to substantially correct said expected inter-frame changes; and a module configured to store the plurality of coefficients in image metadata associated with the images.

1. A system for processing images of a scene captured by an airborne or space based imaging platform, the system comprising:
a correction processor configured to determine a plurality of coefficients associated with a combination of eigenfunctions, including at least any two of an eigenfunction that describes rotational inter-frame changes, an eigenfunction that describes inter-frame focal length changes, an eigenfunction that describes inter-frame anamorphic stretch in one direction, and an eigenfunction that describes inter-frame anamorphic stretch at 45 degrees, the combination of eigenfunctions corrects inter-frame changes in the images that are expected due to induced motion by the airborne or space based imaging platform moving along a trajectory, the plurality of coefficients being determined based on the trajectory and viewing geometry of sensors on the airborne or space based imaging platform; a transformation processor configured to transform the captured images using said plurality of coefficients and the combination of eigenfunctions so as to correct said expected inter-frame changes; and a module configured to store said plurality of coefficients in image metadata associated with said images.
