Colorimetric analysis of images in the follow-up of infantile hemangiomas.

Background/objectives: Infantile hemangiomas (IH) are common vascular tumors that appear early in life, have a rapid proliferative phase and slowly involute. There are no standardized ways to evaluate the regression of these lesions. We propose a colorimetric analysis of photographs to allow a more precise determination of IH treatment response and involution.
