ImageMagick sends messages to stderr to permit a user to redirect their images to one file and metadata information to another. Here compare redirects the difference image to another process and displays the metric to the terminal:
  • -> compare -metric mae image.png reconstruction.png - | convert - -resize 50% difference.png
