Abstract
A method involving filters of an extracted plane from a digital image of an area of skin to obtain a first ripple image and a second roughness image, from which appropriate computation devices are used to calculate different types of gray levels to characterize a pigment spot, notably with regard to the uniformity or disparity of the spot. A method measures the effectiveness of a cutaneous pigment spot treatment by an active pigmenting or depigmenting agent.
