This process is very similar to the general markerless tracking approach presented in the be- ginning of this chapter. This thesis develops a system which integrates most of these stages. The prediction is omitted, though. There is no data available that could provide a sensible prediction. Therefore, the system does not require a probability either. The system is however structuredinawaywhichmakesiteasytoincludeaprediction,iftheneedorpossibilityarises. In Mobile AR, additional sensors like a compass could enable a prediction.
