Abstract:
A method for representing a movie having an original frame sequence, comprising:generating a pixel level frame to frame correspondence;representing the original frame sequence as a multi-image morph, wherein representing the original frame sequence as a multi-image morph comprises representing each frame in the sequence as a point (a.sub.1, a.sub.2, . . . , a.sub.n) in an n-dimensional affine morph space defined by a set of warping mappings W.sub.i and associated color definitions f.sub.i (1.ltoreq.i.ltoreq.n) , where each a.sub.i is a number and each W.sub.i and f.sub.i is an operator on a planar image space, the coefficients a.sub.i satisfying the constraint a.sub.1 +a.sub.2 + . . . +a.sub.n =1;deriving from the multi-image morph a morph basis of feature vectors describing principal changes among frames; andrepresenting the movie in terms of the morph basis.
