Intermediate results obtained using the algorithm that automatically recognizes ROI and skin areas subjected to laser intervention. Right column shows input images L while left column shows images that represent the difference of input image L and its morphological closing. The left column is thus an intermediate result. At subsequent steps of the algorithm visible clear ROI areas are approximated by square areas resulting from forcing shape. Even at this stage of analysis inaccurate covering of skin surface by laser pulses is seen. Pulse overlapping or stacking may lead to heat accumulation.
