Localization of the Vortices and Road Sings in Images

An image in one color is a scalar field. The image is associated with its vector gradient field. The analysis of vector fields with the help of single-length vector templates made it possible to indicate in the image such objects as vortices, Road Signs (RS), Facial Features (FF), and so on. The proposed method of indicating local objects using gradient fields turned out to be highly precision and noise-immunity. The presented advantages of the proposed method recommend it as a promising tool in targets designation problems.
