A common task is to assess the blurriness of a folder of images. Here’s a short script that will do that for us:

$ for f in *.{png,jpg}; do echo -n "$f "; ml blurry opencv $f; done
street_img1.png Okay 610
street_img2.png Okay 481
street_img3.jpg Blurry 64
street_img4.jpg Okay 903
street_img5.jpg Blurry 91
street_img6.jpg Blurry 71
street_img7.jpg Blurry 75
street_img8.jpg Blurry 60
