摘要
真皮表面皮沟和皮嵴的几何特征能反应出人体皮肤的老化程度,而提取几何特征的一个重要预处理是将皮沟和皮嵴进行分割。文章提出了一种边缘空间重叠度的阈值分割方法来自动地分割皮沟和皮嵴。该方法主要通过比较图像间边缘空间的重叠度来计算出图像的阈值。与几种传统的阈值分割方法作对比实验,结果表明,该方法确定的阈值能更准确地分离皮沟和皮嵴。
The geometric characteristics of the leather surface furrow and ridge can reflect the degree of aging of human skin,and an important preprocessing for extracting geometric features is to segment the skin furrow and ridge. A threshold segmentation method of edge spatial overlap degree is proposed to automatically segment the furrow and ridge. This method is mainly to calculate the threshold value of the image by comparing the spatial overlap degree between images. Compared with several traditional threshold segmentation methods,the experimental results show that the proposed method could determine the threshold value more accurately.
