中文说明：此研究目前不对称边界不规则、 颜色变化、 直径 (ABCD) 的特征提取图像了解电子皮肤镜黑色素瘤皮肤癌症诊断。ABCD 特征是基于图像了解电子皮肤镜病变形态学分析的重要信息。ABCD 功能用来为黑色素瘤皮肤癌症诊断计算总了解电子皮肤镜值 （TDV）。不对称特征包括信息不对称和延长指数的病变。边界不规则特征包含的压实度指数、 分形维数、 边缘的唐突和从病变部位色素沉着过渡的信息。颜色均匀性特征包含颜色均匀性和分光光度法和几何形状的病变的相关性的信息。直径提取是病变部位的直径。有三个用于本研究即恶性黑色素瘤，可疑和良性皮肤病灶的诊断。实验使用 30 个样本是可疑恶性黑色素瘤皮肤癌的图像了解电子皮肤镜病变。试验的基础，系统的精度是有四个假诊断的 30 个样品的 85%。
English Description：
This research present asymmetry, border irregularity, color variation, and diameter (ABCD) feature extraction of image dermatoscopic for melanoma skin cancer diagnosis. ABCD feature is the important information based on morphology analysis of image dermatoscopic lesion. ABCD feature is used to calculate Total Dermatoscopic Value (TDV) for melanoma skin cancer diagnosis. Asymmetry feature consist information of asymmetry and lengthening index of the lesion. Border irregularity feature consist information of compactness index, fractal dimension, edge abruptness, and pigmentation transition from the lesion. Color homogeneity feature consist information of color homogeneity and the correlation between photometry and geometry of the lesion. Diameter extraction is diameter of the lesion. There are three diagnosis that is used on this research i.e. melanoma, suspicious, and benign skin lesion. The experiment uses 30 samples of image dermatoscopic lesion that is s
