Abstract:
A method for compression encoding a video signal representative of a plurality of image frames including a starting frame, an ending frame, and at least one intermediate frame, the method comprising:receiving the plurality of image frames; identifying a plurality of feature points for at least one object in at least the starting frame and the ending frame; and for each object: determining a mathematical transformation for estimating a representation of the object in each of the at least one intermediate frame based on an originally received representation of the object in the starting frame and an originally received representation of the object in the ending frame, wherein the mathematical transformation for the object comprises a morphing transformation which maps the identified feature points from the starting frame to the ending frame; encoding the representation of the object in the starting frame; and encoding the mathematical transformation in place of the at least one intermediate frame, wherein the at least one intermediate frame is interpolated based on the encoded starting frame and the encoded mathematical transformation.
