ABSTRACT:
A method and system are provided for generating an output time sequence of image frames from an input time sequence of image frames. For pairs of consecutive image frames of the input time sequence defining a frame rate less than a predetermined output frame rate, a plurality of feature points are identified and located in each of the consecutive image frames. Using the feature points, a first frame of the consecutive image frames is morphed with a second frame of the consecutive image frames to form at least one intermediate frame. The first frame, the at least one intermediate frame, and the second frame are then sequentially organized to form consecutive frames of the output time sequence having the predetermined output frame rate. Pairs of consecutive image frames of the input time sequence having at least the predetermined output frame rate are maintained as consecutive pairs in the output time sequence.
