【摘要】：研究了客观、全面地评价人体面部皮肤状态的方法。为解决目前来源于多个指标的皮肤数据的信息冲突和专家评价标准一致性不佳的问题,结合皮肤状态等级划分的区域特性,提出依据应用调整最佳点位置,对物元法关联函数中的距计算公式进行改进。之后考虑各指标权重在综合评价算法中的重要程度不同,采用层次分析和熵权这两种主客观赋权算法进行优化融合,建立了对人体面部皮肤状态具有较好评价效果的模型。最后,以10名研究对象为例进行实证测试,结果表明相较于经典物元评价模型,改进模型不仅基于的评价标准固定且其评价结果与专家意见具有更高的一致性,二者的吻合度达到了90%。可见,该方法能有效地结合皮肤多指标的实际分布特性进行系统的综合评价,为后续评价算法替代专家进行皮肤诊疗提供了理论支撑。
[Abstract]:In order to solve the problem of information conflict of skin data from multiple indicators and poor consistency of expert evaluation criteria, the methods of evaluating human facial skin state objectively and comprehensively are studied. According to the regional characteristics of skin state classification, the optimal point position is adjusted according to the application. The distance calculation formula in the matter element method correlation function is improved, and the importance degree of each index weight in the comprehensive evaluation algorithm is considered. Two subjective and objective weighting algorithms, AHP and entropy weight, are used to optimize the fusion, and a model is established to evaluate the skin state of human face. Finally, 10 subjects are taken as an example for empirical test. The results show that compared with the classical matter-element evaluation model, the improved model is not only based on fixed evaluation criteria, and its evaluation results are more consistent with the expert opinion. This method can effectively combine the actual distribution characteristics of skin multi-index for systematic comprehensive evaluation, and provide theoretical support for the follow-up evaluation algorithm instead of experts for skin diagnosis and treatment.
