Patent ID: 7463778

Claim:
A machine-implemented method of encoding a target image of a scene captured at a first image plane, comprising: computing a transformation (H) mapping at least three noncollinear points substantially coplanar on a scene plane in the target image to corresponding points in a reference image of the scene captured at a second image plane different from the first image plane; ascertaining an epipole (e REF ) in the reference image from at least one point in the target image off the scene plane and at least one corresponding point in the reference image; determining respective values of a scalar parameter Θ that map blocks of points in the target image to respective matching blocks of points in the reference image in accordance with a motion model corresponding to {right arrow over (b)} REF =(H·{right arrow over (b)} TARGET )+Θ·{right arrow over (e)} REF , wherein {right arrow over (b)} TARGET is a vector that represents a point within a respective one of the blocks of the target image and {right arrow over (b)} REF is a vector that represents a point within a respective one of the blocks of the reference image; and compressing the target image, wherein the compressing comprises encoding ones of the blocks of the target image in terms of the reference image and the respective vectors {right arrow over (b)} REF that are specified by respective ones of the determined values of the scalar parameter Θ.
