Methods and systems for image processing are provided. A method for processing images of a scene includes receiving image data of a reference and a current frame; generating N motion vectors that describe motion of the image data within the scene by computing a correlation function on the reference and current frames at each of N registration points; registering the current frame based on the N motion vectors to produce a registered current frame; and updating the image data of the scene based on the registered current frame. Optionally, registered frames may be oversampled. Techniques for generating the N motion vectors according to roll, zoom, shift and optical flow calculations, updating image data of the scene according to switched and intermediate integration approaches, re-introducing smoothed motion into image data of the scene, re-initializing the process, and processing images of a scene and moving target within the scene are provided.

What is claimed is: 1. A method for processing images of a scene, comprising:receiving image data of a reference frame and a current frame;selecting N registration points in the reference frame by identifying a plurality of candidate registration points in the reference frame based on at least one of an intensity value and an edge metric value, and selecting N registration points from among the identified candidate registration points based on a shape of an autocorrelation function;generating N motion vectors that describe motion of the image data within the scene by computing a correlation function on the reference and current frames at each of the selected N registration points;registering the image data of the current frame using a mapping of the motion of the scene derived from the N motion vectors to produce a registered current frame; andcombining the image data of the registered current frame with image data of at least one previously registered frame to update the image data of the scene by spatially aligning the image data of the registered current frame with the image data of the at least one previously registered frame.
