Remove background in batch

[ricardo7227]

Hello guys, Im new in this software.
I need to remove background of multiple images, i try with this code:

Code: Select all

composite -compose difference overlay.jpg background.jpg diff.png
convert diff.png -threshold 2600 mask.png
convert overlay.jpg mask.png -alpha off -compose CopyOpacity -composite Final.png

and it works!!
example:
original

background

Result:


Although, How i can convert this code for a batch?


But i don´t know how to use mogrify.
Thank you very much.

see

But mogrify will only allow one image in the command line, except for a pre-prepared composite image. So if you cannot make your commands into one convert command with one image and one overlay, then you will need to write a script loop over all the files you want to process.

You should change your composite command to a convert and then try to make all three commands into one convert.

With two composites, I do not think you can use mogrify. You would have to run one mogrify to do the difference and another on the results of the first to do the copy_opacity.
