Abstract: 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 ... (Update)

...estimate in region n. We assume that the regions have been segmented into a finite number of classes based on their motions and average colour [10]. The smoothing algorithm operates by iteratively visiting each region in turn and updating the motion as follows: b (i 1) n =...
...illustrated in Fig. 1.4c. The set of 2 D Gaussians is an ideal choice since it is closed under the operation of the affine transformation [150]. The representation referred to as the g blob representation is temporally persistent and the affine motion estimator discussed...
