摘要: 皮肤表面纹理或微轮廓的量化评价对抗皱宣称的化妆品功效评价有重要意义。基于皮肤美容领域的应用需求和日常生活的实际需要,结合图像处理领域的相关算法,对皮肤的基础纹理特征展开了研究。首先,将实验实测的皮肤图像转为灰度图像,再通过对比度受限的自适应直方图均衡化对图像进行增强,之后通过高斯滤波去除图像的噪声,再采用维纳滤波对纹理的细节信息进行增强,得到纹理清晰的皮肤图像。通过实验确定适合于皮肤纹理评价的灰度共生矩阵的灰度级数和距离,基于灰度共生矩阵算法对皮肤纹理进行统计分析,提出了基于4个纹理特征参数的综合指标数学模型,并应用该模型对全部皮肤图像进行了纹理特征定量评价,同时也由专家对这些皮肤图像进行视觉盲评,2种评价方法一致性良好。

Abstract: Quantitative evaluation of skin texture or micro-contour is of great significance for evaluating the efficacy of cosmetics against wrinkles.Skin texture,as one of the inherent characteristics of the skin,has a significant effect on skin quality.Based on the application requirements of skin beauty and the actual needs of daily life,the basic texture features of the skin were studied by the related algorithms in the field of image processing.Firstly,the experimentally measured skin image was transformed into a grayscale image.The image was then enhanced by contrast limited adaptive histogram equalization.Then the noise of the image was removed by Gauss filtering,and the details of the texture were enhanced by Wiener filtering.A clear texture of the skin image was obtained.The gray scale and distance of gray level co-occurrence matrix suitable for skin texture evaluation were determined through experiments.The skin texture was statistically analyzed based on gray level co-occurrence matrix algorithm.A mathematical model of comprehensive index based on four texture feature parameters was proposed,and the texture features of all skin images were quantitatively evaluated by using the model.Visual evaluation of these skin images was also conducted by experts.The two methods of evaluation are in good agreement.

Key words: cosmetic efficacy evaluation, skin texture, image preprocessing, gray level co-occurrence matrix algorithm, synthesis index
