| description | The invention discloses a method for automatically extracting and quantifying the color of a lesion area of an infantile hemangioma. The method comprises the steps of extracting a lesion part in an image of the infantile hemangioma, marking the lesion part as the lesion area and marking the remaining part as a skin area; converting color space of the lesion area and the skin area from red green blue (RGB) to international commission on illumination (CIE) Lab; extracting a mean value of chromatic values of three channels of the skin area to obtain a mean vector of the chromatic value of the skin area; extracting the mean value of chromatic values of three color channels of the lesion area to obtain the mean vector of the chromatic value of the lesion area; calculating distance by utilizingthe mean vector of the chromatic value of the skin area and the mean vector of the chromatic value of the lesion region, wherein the distance comprises Euclidean distance, Manhattan distance, Chebyshev distance, included angl |
