input.png contains the best single-light white balance result

* in order to get linearized values, you have to apply inverse gamma correction, with gamma = 2.2

input_original.png contains the original input image

* if the single-light white balance was done at shooting time, this image is not provided, as it is the same as input.png

neutral_color_scribbles.png contains the neutral-color scribbles, if any were used

* this is a grayscale image, where non-zero values indicate neutral pixels

correct_color_scribbles.png contains the correct-color scribbles, if any were used

* this is a grayscale image, where non-zero values indicate regions that, according to our user, look good in the input image (input.png)

same_color_scribbles.png contains the same-color groups, if any were used

* this is a grayscale image, where pixels that should share the same chromaticity are marked with the same, non-zero, gray value

our_result.png contains the final result of our system

ground_truth.png contains the ground truth solution, when available
