Abstract:
A method of generating a non-repetitive output time sequence of image frames in a continuous full motion video stream, from a lesser input time sequence of full motion video image frames, the method comprising the steps of:(a) receiving as part of the input time sequence of full motion video image frames a pair of consecutive image frames of the input time sequence of full motion video image frames, the pair of consecutive image frames including a first frame and a second frame, the pair of consecutive frames defining a frame rate less than a predetermined frame rate;(b) identifying and locating a plurality of feature points in both the first frame and the second frame;(c) morphing the first frame with the second frame using the plurality of feature points to form at least one intermediate frame;(d) sequentially organizing the first frame, the at least one intermediate frame, and the second frame to form consecutive frames of the output time sequence;(e) receiving a second pair of consecutive image frames of the input time sequence differing from the first pair received in step (a), second pair of consecutive image frames including a third frame and a fourth frame, the second pair defining a frame rate which is at least the predetermined frame rate; and(f) maintaining the second pair of consecutive image frames as image frames in the non-repetitive output time sequence;wherein the consecutive frames of the non-repetitive output time sequence define a non-repetitive full motion video stream having a frame rate which is at least the predetermined frame rate.
