From 21.03.04 to 26.03.04, the Dagstuhl Seminar 04131 Geometric Properties from Incomplete Data was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The rst section describes the seminar topics and

It has often been criticised that there is no reliable condence measure that allows to sparsify the result of a dense ow eld such that the remaining ow is more reliable. In this way it would be possible to compare the real quality of dense methods with the characteristics of local, nondense approaches. In our paper we investigate the usefulness of local image based condence measures for global variational methods and present a ow based alternative that is simple and applicable to the entire class of energy minimising global optic ow techniques. Experimental evaluation on various images sequences will show that this condence measure can give excellent results.
