摘要

PROBLEM TO BE SOLVED: To estimate a dominant motion between frames in image sequences or video sequences.

SOLUTION: A method of representing a 2-dimensional image comprises deriving at least one 1-dimensional representation of the image by projecting the image onto at least one axis, and applying a Fourier transform to the 1-dimensional representation. The representation can be used for estimation of dominant motion between images.
