What are some easy-to-apply filters in ImageMagick?
I have started using ImageMagick for pre-processing images for machine learning. I want to test of the effect of different filters on my algorithms.
So far, I have used grayscale like so :
magick mogrify -colorspace gray *.jpg
to apply a grayscale filter.
What are some other filters/how can I apply them to entire folders easily for testing their impact on CNN score results?
Thanks!

Mogrify will process whole folders of images. See imagemagick.org/Usage/basics/#mogrify. Some filters to try are -blur, -statistics median, -selective-blur, -auto-level, -resize. See imagemagick.org/script/command-line-options.php, imagemagick.org/Usage/reference.html, imagemagick.org/Usage
