Patent Images

1. A method of frame registration of images comprising:

  • generating a first plurality of projections from a first frame;

    generating a second plurality of projections from a second frame;

    comparing a first set of projections amongst the first plurality of projections with a second set of projections amongst the second plurality of projections, and generate a set of projection correlation error (pce) values;

    selecting the first frame and second frame based on a parity of a number of total frames to be processed in a row from a frame flow-tree, wherein the frame flow-tree includes a tree of frames where leaf nodes include unregistered frames and other nodes include registered frames that are based on their respective child nodes;

    generating a component of a global motion vector estimate by selecting a minimum pce value from among the set of pce values; and

    adding the estimated global motion vector to the first frame.
