Abstract
Stabilization for devices such as hand-held camcorders segments a low-resolution frame into a region of reliable estimation, refines the motion vectors of that region hierarchically while at the same time updating the segmentation, finds a global motion vector for the region at high resolution, and uses the global motion vector to compensate for jitter.
