Estimation of transparent motions with physical models for additional brightness variation |
Abstract | ||
|---|---|---|
The paper deals with the estimation of complex motion pat- terns. The complexity is due to (i) the motions of two trans- parent layers, and (ii) an additional change of brightness i n the layers, which can be due to an additive source term, an exponential decay, or diffusion. We present new models and constraints for such complex motion patterns. Exper- iments on synthetic image sequences demonstrate the per- formance of our models in conjunction with a total least- squares parameter estimation scheme. Crucial ingredients of this scheme are new filter families of derivative filters of up to fourth order. We present a procedure for how to construct appropriate filter families for the introduced models. |
