Colour - Checker Detection - 0.2.0

This release introduces machine learning inference for the detection of the ColorChecker Classic 24.

Features

colour_checker_detection.detection

Machine Learning Inference

• Add colour_checker_detection.detection.detect_colour_checkers_inference definition. (#75, @KelSolaar)

The model used for inference is published on HuggingFace, and was trained on a purposely constructed dataset.

The model has only been trained on ColorChecker Classic 24 images and will not work with ColorChecker Nano or ColorChecker SG images.

Inference is performed by a script licensed under the terms of the GNU Affero General Public License v3.0 as it uses the Ultralytics YOLOv8 API which is incompatible with the BSD-3-Clause.

Fixes

• Fix incorrect colour checker flipping detection in colour_checker_detection.detection.detect_colour_checkers_segmentation definition. (#73, @andieich, @mexicantexan, @KelSolaar)

Changes

• The colour_checker_detection.detection.detect_colour_checkers_segmentation definition has been overhauled to provide a consistent interface with the colour_checker_detection.detection.detect_colour_checkers_inference definition. It also features some improvements following discussions with contributors. (#53, #73, #74, @andieich, @mexicantexan, @TimWalter, @KelSolaar)
