| 中文摘要: |
| 目的 基于人眼长期观察实践对色彩形成的认知以及识别肤色时的主观偏好记忆性， 对偏好记忆的肤色进行获取以及再现。方法 选取代表人群拍摄肤色数据， 并通过心理物理试验获取偏好肤色数据库， 采用YCbCr空间建立椭圆模型对肤色和偏好肤色分布进行模拟。利用椭圆模型， 提出一种基于仿射变换的偏好肤色再现算法。结果 实现了输入图像中肤色到偏好肤色的转换和再现， 并使用瑟斯顿成对比较法对仿射变换再现算法和其他算法的再现效果进行了评价。结论 算法具有较高的观察者偏好度， 更符合人们的主观感受， 肤色再现效果较好。 |

| The aim of this study was to realize the transformation of skin colors from detected skin color to preferred one considering cognition formed from long-time observation practice on colors and subjective preference for memory skin colors. The database of preferred skin was established by selecting representative populations, photographing skin color data and psychological physical tests, and an elliptical model was built using YCbCr color space to simulate the distribution of skin colors and preferred skin colors. Using this elliptical model, a preferred skin color reproduction algorithm based on affine transformation was proposed in this paper. Transformation and reproduction of preferred skin colors from detected skin colors were realized in the input images. And Thurston′ s Law of Comparison was used to evaluate the reproduction results of the affine transformation reproduction algorithm and other algorithms. The proposed algorithm was better in preferred skin color reproduction in most cases and was subjectively preferred. |
