Use "compare" but avoid the "difference" file

Post by acb764se »

Hi,

I would like to compare two similar pictures from my own security cameras, possibly testing different metrics, but have no use for the "difference" file, is there an option to avoid generating one?

thanks!

Put NULL: in place of the output filename.
