Implementation of the fast algorithm for geometrical coding of digital images with the use of CUDA architecture

In this paper we compare the speed and quality of CUDA realization for new contour detection algorithm based on geometrical coding with CUDA implementation of Canny algorithm which is commonly used in OpenCV library. The comparison shows that the new approach can really compete with the Canny operator and in some cases even overcome it in speed and quality. Examples of geometrical coding contour detection in different situations are presented.
