Features of image contourization algorithms: accumulated data from the Shack-Hartmann sensor

The paper discusses the problems of contourization of images of solar objects obtained in the focal plane of the Shack-Hartmann sensor, the main element of the layout of the adaptive optics system of the Large Solar Vacuum Telescope. An algorithm for recognizing subaperture boundaries and sunspot contours is proposed. The algorithm is based on image filtering and John-Canney methods.  The results obtained can be used in estimating the characteristics of atmospheric optical turbulence.
