De data is al maanden binnen, het worstelen ermee is nog niet afgelopen. De registratie gaat prima, maar ik blijf nog problemen houden met het “dambord” effect (Of Illumination wave effect) zoals vooral goed te zien is rechtsonder op deze (tot 15% teruggeschaalde) inverse weergave van 25 panelen. Ik gebruik de 1.059 APP versie en heb in overleg met Mabula nu deze instellingen gebruikt als uitgangspunt:

“For the individual mosaic panels:

  • LNC 1st degree 3 iterations
  • MBB at 5-10%

For the mosaic:

  • LNC 2nd – 4th degree 3 iterations (only increase iterations and degree if needed) A higher degree can cause more illumination waves in the mosaic. (LNC upgrade for this is being worked on)
  • MBB at 10-25% (depends on the amount of overlap between the mosaic panels, 10% overlap -> 10% MBB, 20% overlap -> 20%MBB)

Then the mosaic calculation is reduced to only 9 frames and calculating that is done in a couple of minutes on most hardware. So that will reduce the amount of time needed for registration greatly and it will even give better and more robust registration for your mosaic ”

De LNC upgrade zal verbetering moeten gaan brengen.
