This simple Bash script inspects all images in current dir, and copies those with enough change to a separate dir. The original from laurent22/pmcam grabed images from a webcam. In my case I use a tethered camera that takes images at regular intervals to a date named directory, and then use this script to copy images with enough change to a output directory. Then every now and then I clear the source dir from old pictures.

brew install imagemagick

sudo apt-get install imagemagick

(Not tested)

• Install ImageMagick

The primary config options are:

DIFF_LIMIT       cut-off for what changes should be saved
OUTPUT_DIR       where to save matching imgs
SOURCE_WILDCARD  what images to process
TIME_STAMP       imagemagick code to set a time-stamp
RESIZE           set if images should be resized

Booleans, true/false
REMOVE_SOURCE    Remove source images
DISPLAY_SKIPPED  display info about ignored images
SINGLE_PASS      run once or loop for ever

Set them as you see fit.

cd to dir where images to be processed are located, then run it as:

./pmcam.sh

To stop the script, press Ctrl + C. If REMOVE_SOURCE is set you can stop and resume at any time.
