A fast Algorithm of Gray Scale Projection

The gray scale projection algorithm can detect motion vector of image sequential frames in electronic image stabilization. Three-point adaptive searching algorithm is proposed on the basis of single peak characteristics. The procedures are as follows: through equably selecting three points in searching coverage, judging the variation direction of the correlation curve gradient, the searching parameters will be correspondingly adjusted to obtain the motion vector between frames and then motion filtering and image compensation can be carried out. The algorithm has been demonstrated that the faults of large operation load have been overcome by simulation experiments.
