LinearFit Incompatible Geometry Error
« on: 2017 March 17 14:07:08 »
When I try to apply an RGB to a Lum using LinearFit, I get an incompatible geormetry message.  These are two images that were successfully used to create an LRGB using LRGBCombination.  What can cause this message?

geometry includes the # of planes in the image... you can't linear fit a 3-plane image to a 1-plane image...

i guess you could extract the L* from the RGB and then linear fit that to the L...

Thanks, that eliminated the error.  I will try to remember the third dimension of an rgb.
