Re: [OSSIM] Histogram matching

[Spot <spo...@gm...>]

Hi!

Perhaps that helps finding the error.
When the merged image is created, imagelinker shows all three images one
above the other. I have to use the "fit" button first for the parts to
move to their correct location.
I didn't have that problem with the color images I processed before.
Perhaps there is some problem with geocoding already in this step and
not later when saving the file.

I hope that doesn't annoy you too much but I love this function and
would like to use it in my work...
