Instead of adapting the threshold to the image before executing commands, adapt the threshold just before it is needed. This allows to avoid theshold adaptation when -p, --process-only is used with only the "grayscale" and/or "mirror" commands. This also prepares the code to allow introduction of a new option to avoid adapting the threshold to the original image before the "crop" command is applied.
