Simple library for debayering images with OpenCV.
See the Wikipedia article on the Bayer filter for more information.
pip install simple-image-debayer
You can use the sid-debayer command-line tool for debayering directories:
usage: sid-debayer [-h] -i DIR [-I EXT] [-r] [-o DIR] [-O EXT] [-c PROFILE]
[-p NUM] [-e] [-d] [-v] [-n]
Debayers images in a directory.
optional arguments:
-h, --help show this help message and exit
-i DIR, --input_dir DIR
the directory to process (default: None)
-I EXT, --input_ext EXT
the extension to look for in the input directory
(default: bmp)
-r, --recursive whether to look for images recursively (default:
False)
-o DIR, --output_dir DIR
the directory to store the debayered images in;
performs in-place debayering if not specified
(default: None)
-O EXT, --output_ext EXT
the extension to use for the generated images
(default: jpg)
-c PROFILE, --color_profile PROFILE
the OpenCV color profile to use for debayering
(cv2.COLOR_BAYER_*) (default: COLOR_BAYER_BG2BGR)
-p NUM, --progress_interval NUM
the interval of processed images to output progress
information in the console (default: 100)
-e, --ignore_errors whether to ignore any errors and keep debayering
(default: False)
-d, --delete whether to delete the input file after successfully
debayering it (default: False)
-v, --verbose whether to output directories being processed
(default: False)
-n, --dry_run whether to perform a dry-run; --verbose should be used
in conjunction with this flag (default: False)
Of course, the tool can be used as a Python library as well.
The module sid.debayer contains the following methods among others:
debayer_dir- for debayering a directory (that is the main routine)debayer_file- for debayering a single filedebayer_image- for debayering an in-memory image (in/out:ndarray)read_image- reads a bayered image into memory (out:ndarray)write_image- writes a debayered image to disk (in:ndarray)eval_color_profile- turns the color profile string (e.g.,COLOR_BAYER_BG2BGR) into an integer constant (e.g.,cv2.COLOR_BAYER_BG2BGR)
