Slow Mosaic integration 20+hrs

Nevermind I think i found my answer in another post.  Create each panel separately then do the mosaic.

Hi Netboy,

Yes, it's most efficient to first create the panels and then create the mosaic from the panels. The reason being: If you load all single frames (4*30=120) then the mosaic algorithm needs to find the registration parameters( for both the projective transformation and the and optical distortion correction) for all 120 frames all at once. This is a huge calculation and therefore will take very long. The calculation in the end finds 120 *16 parameters = 1920 ! parameters. If you create the 4 panels and then register them as a mosaic, the algorithm only needs to calculate 4x16 = 48 parameters and this should be finished in a couple of minutes on your i7 I think.

On a sidenote, in the next APP version 1.054 (which I try to release before mondag) a strongly improved mosaic algorithm is introduced which might very well give a better registration for the whole mosaic, it will be more robust and quicker. Details here:
