Fig. 8From: Hyperpigmentation after surgery for a deep dermal burn of the dorsum of the hand: partial-thickness debridement followed by medium split-thickness skin grafting vs full-thickness debridement followed by thick split-thickness skin graftingThree-dimensional(3D) histograms in the hue, saturation, and brightness (HSB) color space. The shape formed by the histogram dots was similar between the control and graft areas in the full-thickness debridement (FTD) group, but not similar between the control and graft areas in the partial-thickness debridement (PTD) groupBack to article page
