How it works

Running

To run the script:

python scammer.py path_to_csv.csv

The csv file contains a list of image folder or s3 prefix that will be cropped. Currently only the first column is read, see todo.csv for an example. The second column is read. It is a colon separated list of operations, known as a pipeline. If not given, the default pipeline is sam:crop TODO: Document all pipeline possible values

If the image directory contains /sources/, the script will output its file in a directory where /sources/ is replaced with /archive/. Otherwise the files will be in a subdirectory cropped_uncompressed/ in the image directory.
