皮肤病变颜色是诊断恶性黑色素瘤的重要特征。提出了一种新的基函数相关特征，用于皮肤镜图像中恶性黑色素瘤病变与良性黑色素瘤病变的鉴别。所提出的特征是基于将来自皮肤病变指定部分的黑色素瘤或良性标记相对颜色的亮度直方图与一组基函数相关联来计算的。这些特征扩展了先前开发的基于统计和模糊逻辑的相对颜色直方图分析技术，用于从病变图像的训练集中自动映射黑色素瘤和良性皮肤病变的代表颜色。使用基于统计和模糊逻辑的相对颜色映射方法，分别在感兴趣的皮肤病变区域上计算黑色素瘤和良性颜色特征。亮度直方图是从感兴趣的病变区域内的黑色素瘤和良性映射颜色中获得的，并与一组基函数相关联，以量化颜色的分布。直方图分析技术和特征计算使用279个恶性黑色素瘤和442个良性发育不良痣图像的数据集进行评估。实验测试结果表明，将现有黑色素瘤和良性病变的颜色特征与从黑色素瘤映射颜色中找到的提出的基函数特征相结合，平均正确的黑色素瘤和良性病变识别率分别高达86.45%和83.35%。基函数特征为黑色素瘤鉴别提供了另一种方法，量化黑色素瘤和良性皮肤病变特征的颜色变化和分布。
Skin lesion color is an important feature for diagnosing malignant melanoma. New basis function correlation features are proposed for discriminating malignant melanoma lesions from benign lesions in dermoscopy images. The proposed features are computed based on correlating the luminance histogram of melanoma or benign labeled relative colors from a specified portion of the skin lesion with a set of basis functions. These features extend previously developed statistical and fuzzy logic-based relative color histogram analysis techniques for automated mapping of colors representative of melanoma and benign skin lesions from a training set of lesion images. Using the statistical and fuzzy logic-based approaches for relative color mapping, melanoma and benign color features are computed over skin lesion region of interest, respectively. Luminance histograms are obtained from the melanoma and benign mapped colors within the lesion region of interest and are correlated with a set of basis functions to quantify the distribution of colors. The histogram analysis techniques and feature calculations are evaluated using a data set of 279 malignant melanomas and 442 benign dysplastic nevi images. Experimental test results showed that combining existing melanoma and benign color features with the proposed basis function features found from the melanoma mapped colors yielded average correct melanoma and benign lesion discrimination rates as high as 86.45% and 83.35%, respectively. The basis function features provide an alternative approach to melanoma discrimination that quantifies the variation and distribution of colors characteristic of melanoma and benign skin lesions.
