In this paper we observe that information theoretical concepts are valuable tools for extracting from images and, in particular, on image symmetries. It is shown the problem of detecting reflectional and rotational symmetries a two-dimensional can be reduced to point-symmetry periodicity one-dimensional negentropy functions. Based these findings detector global greyscale constructed. We discuss importance high precision symmetry detection applications arising quality control illustrate how proposed method satisfies requirement. Finally, superior performance our other existing methods, demonstrated by results rigorous experimental verification, an indication approach rooted theory promising direction development robust widely applicable detector.
