Computer-Vision-Based Identification of Nail´s Surface Shape

This article presents the principle and application of a computer-vision-based method of identifying the surface shape of human´ s nail. The method first acquires two images of a human nail respectively with the same light source but different light angles, obtains from the two images the information on the nail and calculates the surface shape of the nail in the end. The main algorithm of obtaining the surface shape of nails is given in the article.
