One means of bypassing this obstacle is through multi scale flow recovery, essentially a sampling of the signal at different frequency values [36]. As a comparison to Figure 36a, a network consisting of 625 nodes placed exactly at the grid locations provides the best measure of what can be achieved.

....whole optic flow vector map of dimension 2N if the frames have N pixels. A similar approach has been proposed by Weber and Malik in 1995 [31] They use real valued functions of several scales to filter the OF equation, which makes their approach computationally more expensive. Simoncelli et al. [27] proposed a Bayesian estimation resolution method of multiscale differential constraints, and Magarey and Kingsbury [21] an approach based on the minimization of subband squared image differences. The former uses a real steerable pyramid as a set of filters, and the latter use analytic wavelets ....
....the optic flow and (2) rely on a looser assumption (A) on the flow field uniformity. However, coarse scale measurement are less subject to time aliasing as indicated in (9) In this approach, we follow the path already opened by several authors in various flow measurement methods [9] 3] 31] [27] [21] to combine informations from several scales in the following way: large displacements are measured first and at large scales. Then, the resulting motion is compensated so that the residual motion is smaller and stays within the alias free range of the finer scale subsystems. Assume a motion ....
