Implementation of the Fast Algorithm for Geometrical Coding of Digital Images with the Use of CUDA Architecture / A. Yu. Chekunov. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2018. № 6. P. 20-30 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 229-238].

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

Key words: pattern recognition, geometrical coding, coding surface, contour analysis, edge detection, computer vision, image processing, image stitching.
