Analytic solutions for multiple motions

A novel framework for single and multiple motion estimation is presented. It is based on a generalized structure tensor that contains blurred products of directional derivatives. The order of differentiation increases with the number of motions but more general linear filters can be used instead of derivatives. From the general framework, a hierarchical algorithm for motion estimation is derive...

Efficient coding and multiple motions

Based on the principle of efficient coding, we present a theoretical framework for how to categorize the basic types of changes that can occur in a spatio-temporal signal. First, theoretical results for the problem of estimating multiple transparent motions are reviewed. Then, confidence measures for the presence of multiple motions are used to derive a basic alphabet of local signal variation ...

for Typical Hard Ball Systems

We consider the system of N (≥ 2) hard balls with masses m1, . . . , mN and radius r in the flat torus TL = R /L · Z of size L, ν ≥ 3. We prove the ergodicity (actually, the Bernoulli mixing property) of such systems for almost every selection (m1, . . . , mN ; L) of the outer geometric parameters. This theorem complements my earlier result that proved the same, almost sure ergodicity for the c...

Image sequence enhancement using multiple motions analysis

Accurate computation of image motion enables the enhancement of image sequences. Motion computation in scenes having multiple moving objects is performed together with object segmentation by using a unique temporal integration approach. Having accurate motion estimation for image regions, these regions can be enhanced by fusing all successive frames covering the same region. Enhancement include...

Linear and regularized solutions for multiple motions

We extend a novel framework for the estimation of multiple transparent motions to include regularization. We use mixed-motion parameters to obtain linear Euler-Lagrange equations with a regularization term. The equations are solved iteratively for the mixed-motion parameters based on an update rule that is similar to the case of only one motion. The motion parameters are then obtained as the ro...
