The mark area is every pixel that differs from the original by 3 or more on any channel when drawn at opacity 100. “One cut removes it” is the smallest share of the photo a single straight cut from one edge must discard to delete every mark pixel; if that cut enters the subject’s box (boat or mug) it is listed as not possible. “Change” is the mean difference from the original inside the mark area, on a 0–255 scale.",
