肤色测量及其稳定性研究

Research on Influence Factors of Skin Colour Measurement

肤色测量是颜色科学研究及应用的重要课题,广泛应用于机器识别、时尚彩妆以及远程医疗等领域。本研究针对不同肤色测量方法对肤色测量结果的影响进行了分析,对肤色测量仪器的测量参数设定及测量方法进行了评价,并采用笔者所研究建立的全球首个肤色数据库中的160位不同肤色人种及其肤色样本作为肤色数据,深入分析了影响肤色测量稳定性的要素。结果表明,测量面积与测量方式是影响稳定性的关键因素,测量位置与人种则对非接触式测量有一定影响。

The study of the skin colour is an important part of the colour research,and it has wide applications,including computer vision,cosmetics industry and remote medical for dermatology.In this study,the impact of different parameters of the instrument to the skin colour measurement result variation was investigated.Base on the result,a recommendation of skin colour measurement was proposed.Furthermore,the skin colour data of 160 subjects with different ethnicity were used to investigate the effect of the ethnicities and body locations.The results showed that,for contact type of instrument,the measurement method have great influence on the short-term repeatability.The aperture size has greater impact on the interinstrument agreement.For non-contact method,dark skin colour and body location can cause the variation of the short-term repeatability.
