非典型(不规则)色素网络(APN)的存在可以指示黑色素瘤的诊断。本研究试图分析APN与纹理措施。对106例皮肤镜图像,包括28例黑色素瘤和78例良性发育不良痣,手动选择APN区域。应用CVIPtools图像分析系统中的十种纹理度量。在所使用的10种纹理测量中,相关平均值提供了最高的判别准确度,平均为95.4%。对于768 × 512的图像,在像素距离为20时,黑色素瘤的辨别是最佳的,这与黑色素细胞病变纹理像素大小估计为4-5个纹理像素/mm一致。纹理分析,特别是在优化像素间距下的相关平均,可以提供早期恶性黑色素瘤中不规则色素网络的自动检测。
The presence of an atypical (irregular) pigment network (APN) can indicate a diagnosis of melanoma. This study sought to analyze the APN with texture measures. For 106 dermoscopy images including 28 melanomas and 78 benign dysplastic nevi, the areas of APN were selected manually. Ten texture measures in the CVIPtools image analysis system were applied. Of the 10 texture measures used, correlation average provided the highest discrimination accuracy, an average of 95.4%. Discrimination of melanomas was optimal at a pixel distance of 20 for the 768 × 512 images, consistent with a melanocytic lesion texel size estimate of 4–5 texels per mm. Texture analysis, in particular correlation average at an optimized pixel spacing, may afford automatic detection of an irregular pigment network in early malignant melanoma.
