educelab.imgproc.pipeline

Utilities for building processing pipelines on the command line.

from educelab.imgproc import pipeline

# setup the parser
parser = argparse.ArgumentParser()
parser.add_argument('--input', '-i', help='image path')
enhance_opts = pipeline.add_parser_enhancement_group(parser)

# parse arguments and commands
# foo.py -i image.png -- -gamma=0.45 -pstretch=0,99 -sharpen
args = parser.parse_args()
apply_pipeline, _ = pipeline.parse_and_build(args.commands)

# process the image
img = iio.imread(args.input)
img = apply_pipeline(img)
