Zusammenfassung der Projektergebnisse

The pursued research reached all the defined goals of the original grant proposal. As a result a fully automatic motion compensation algorithm was developed, implemented, evaluated, presented at major conferences, and published in highly ranked journals. The developed algorithms for motion compensation are developing to be the most applied method in 3-D OCT imaging due to the huge support of Professor Fujimoto with his team and collaborators. The results also show that the explicit modeling of eye rotation is not required to perform motion compensation in OCT. As expected, nonrigid registration covers all types of eye motion within an OCT acquisition cycle.
