Walter Hinterberger, Otmar Scherzer, Christoph Schnörr, Joachim Weickert · Numerical Functional Analysis and Optimization · 2002
In image sequence analysis, variational optical flow computations require the solution of a parameter dependent optimization problem with a data term and a regularizer. In this paper we study existence and uniqueness of the optimizers. Our studies rely on quasiconvex functionals on the spaces , with . The methods that are covered by our results include several existing techniques. Experiments are presented that illustrate the behavior of these approaches.
