A procedure for adapting the isoline curvature formula to estimate an edge curvature in the images is presented. The curvature estimation is used in the framework of the scale-space algorithm, which makes it possible to choose the required scale adaptively at each point of interest. The procedure for edge points clustering to the subsets, each of which contains the points of one circumference, has been developed to detect the circumferences.
