  • (a) producing an initial set of frames from said video sequence;

    (b) introducing each frame of said initial set sequentially into a 3-frame buffer to include a middle frame M, its preceding frame L, and its succeeding frame R;

    (c) testing for redundancy each M frame with respect to its preceding L frame and its succeeding R frame; and

    (d) selecting as a key-frame for inclusion in the subset those M frames tested to be non-redundant.
