For the qualitative comparison we assessed the correspondences provided by both procedures. The simulations were done on natural images of two objects. Both procedures, tracking as well as matching, proved to be appropriate to generate a distribution of view similarities on the viewing hemisphere. Canonical views arise. We could not find a difference between both procedures concerning the quantitative size criterion, but tracking outperforms matching concerning the qualitative condition.
Tracking provides much more precise correspondences than matching.
The continuous information seems to be neccessary to build the correspondences. Our results are supported by related insights from psychophysical research. Erkenntnissen wird ein System beschrieben, welches zur Klassifikation von Beleuchtungssituationen eines Gesichtes verwendet werden kann. We report briefly on its motivation and history, and highlight the most important aspects of software engineering we have applied in designing this library.
