在本文中，我们提出了一种新的方法来识别手指接触的图像分析，这不会干扰userpsilas触觉。当手指触摸桌面时，其指甲的颜色图案从粉红色变为白色。指甲的外观变化可用于通过相机图像与指尖图像数据库之间的图像匹配来区分手指接触到桌面表面上。由于数据库的高维性，我们采用基于主成分分析（PCA）的EigenNail方法来实现快速图像匹配。
In this paper, we propose a new method to recognize finger contact by image analysis, which does not disturb userpsilas tactile feeling. When a finger touches a desktop surface, the color pattern of its nail changes from pink to white. The appearance change of the nail can be used to distinguish the finger contact onto a desktop surface by image matching between a camera image and a fingertip image database. Due to high dimensionality of the database, we apply EigenNail method based on principal component analysis (PCA) to realize the quick image matching.
