Semi-automatic ColorChecker segmentation

Provide ColorChecker Classic patch segmentations in order from an image via 4 user clicks.

Method to obtain ordered patch segmentations (from brown to white) from images of the ColorChecker Classic card. The user is instructed to click on the four white right-angle fiducials (clockwise or anticlockwise, starting with any corner) and the patches are automatically segmented in order. The segmentations are displayed and the white and yellow patches are labelled to enable a check of the order - the order and segmentation can then be adjusted if required. With this small amount of user input, images captured for any orientation, angle and lighting condition can be processed.
