Ground Truth for Correspondence Problems: What we need to know
Place: Large Lecture Room
Affiliation: HCI Lasb. Heidelberg, Germany
Creating ground truth for e.g. optical flow in natural outdoor environments seems almost impossible. In this talk, I will propose several possible approaches, some of which we are currently investigating. One approach is to use semi-automatic vision algorithms as is done for example in movie postproduction to create 'weak' ground truth. Another method is to evaluate the properties of today's computer graphic rendering systems with respect to their ability to generate images close to the real world. I will also discuss the problems of content selection, defining performance measures and benchmarking with respect to correspondence estimation and related algorithms.
