This paper introduces a new generalisation of the familiar scale-space and wavelet representations, designed specifically to deal with the complexities of representing motions induced in an image sequence by the movement of 3-D objects of which the scene is comprised. It does this by combining an affine representation of local image motions with a local structure model based on Gaussian functions. After a brief review of its symmetry and completeness properties, the representation is applied to the analysis of image motions in a typical video sequence.
