autocrop
A high-performance face-aware crop utility using OSX’s Vision framework.
This utility takes a photo, detect every face in the image file and
save it as a square jpg file in the directory you specified.
Here are a few examples:
# To locate and safe all faces into `Faces` folder
autocrop ~/Documents/Photos/IMG_1772.JPG ~/Documents/Faces/
# To batch process of images, use `find`
find ~/Documents/Photos -name *.JPG -exec autocrop {} ~/Documents/Faces/ \;
# If you need to resize the file to 250x250, use `imagemagick`
find ~/Documents/Faces -name *.jpg -exec convert {} -resize 250x250 {} \;
Improvements
- For a portrait mug shot, we might end up with an image not entirely square.
