基于图像分析的化妆品紧致功效评价方法研究

Evaluation of cosmetics firming efficacy based on image analysis

基于抗衰老功效评价,以图像分析法为依据,参考医学面部评价方法,通过采集使用功效化妆品前后受试者面部图像,应用计算机软件分析受试者面部特征点数据改变规律,寻找研究面部皮肤紧致提升的数据化方法。经验证下半面宽度、鼻唇角、眼部角度A及眼部角度B有统计学意义(P<0.05),应用于抗衰老护肤品紧致及提升面部的功效评价,可通过测算角度改变程度来评价产品功效强弱,补充和完善现有护肤品功效评价方法,使评价体系更加丰富立体。

Based on the evaluation of anti-aging efficacy,on the basis of image analysis method and referring to medical facial evaluation methods,by collecting the subjects’facial images before and after using the functional cosmetics,and using computer software to analyze the changing rules of subjects’facial feature point data,a databased method for the study of facial skin firmness was found.It is proved that the lower half width,nasal-lip angle,eye angle A and eye angle B are statistically significant(P<0.05),which can be used to evaluate the efficacy of anti-aging skin care products to firm and lift the face.The efficacy of the product can be evaluated by measuring the degree of change in the angle,supplement and improve the existing efficacy evaluation methods of skin care products,and make the evaluation system richer and more stereoscopic.The existing skin care efficacy evaluation methods can be supplemented and improved to make the evaluation system more abundant and stereoscopic.
