Claim One:
1. A method for stabilization of image data by an imaging device, the method comprising the acts of: detecting image data for a first frame; detecting image data for a second frame; performing motion estimation based on image data for the first and second frames to determine one or more motion vectors associated with global frame motion for image data of the first frame; performing an outlier rejection function to select at least one of the one or more motion vectors, wherein the outlier rejection function employs a sparse set of selected and weighted image locations within the first frame to select the one or more motion vectors; determining a global transformation for image data of the first frame based, at least in part, on motion vectors selected by the outlier rejection function and on a confidence measure that the global transformation will exclude non-global estimations; determining a stabilization transformation for image data of the first frame by refining the global transformation to correct for unintentional motion, wherein the refining employs recursive filtering to smooth at least a portion of the global transformation that is separate from at least a rolling shutter artifact included with the global transformation; and applying the stabilization transformation to image data of the first frame to stabilize the image data of the first frame.
