Скелетизация полутонового изображения на примере изображений отпечатков пальцев

In this article the grayscale image skeletonization problem is shown by the example of images of fingertips prints. The main idea: the grayscale image skeleton is constructed using some parts of binary images skeletons. One can take these binary images after initial grayscale picture binarization with various brightness levels. Such binary images skeletons fragments give us the opportunity constructing clear binary image of initial grayscale picture. By this clear binary image one can construct the final skeleton; this skeleton allows comparing of particular points of a finger papillary pattern. This final skeleton is concerned as a skeleton of a grayscale image.
