Method for determining facial skin color and corresponding system

A method for determining a skin color of a region of interest of a user comprises:-importing from an image library (LIB) of a user computing device (APP) at least one image (IMk) comprising a representation of the region of interest of the user; -performing a process (TS) on said at least one image (IMk) with a machine learning model (AITS) adapted to provide, for each imported image (IMk), a numerical value (ClrEstmk) representative of the skin color of the region of interest present in said at least one imported image (IMk); -performing an evaluation (EVAL) of the skin color of the region of interest on the basis of the one or more values (ClrEstmk) of each imported image. 一种用于确定用户关注区域的皮肤颜色的方法包括：-从用户计算设备(APP)的图像库(LIB)导入包括该用户关注区域的表示的至少一个图像(IMk)；-用机器学习模型(AI_TS)对所述至少一个图像(IMk)执行处理(TS)，该机器学习模型适合于为每个导入图像(IMk)提供代表所述至少一个导入图像(IMk)中存在的该关注区域的皮肤颜色的数值(ClrEstm_k)；-基于每个导入图像的所述一个或多个数值(ClrEstm_k)对该关注区域的皮肤颜色执行评估(EVAL)。
