Abstract. The proposed work describes the application of digital image processing techniques for the virtual reconstruction of widely known works of fine art. Firstly, it is the  Interpolation Method of Sequential Computation of the Fourier spectrum (IMSCS) that allows you to retouch and restore the missing (shaded) parts of the image. Secondly, these are the methods of increasing the images contrast (converting the dynamic range of brightness), such as Dark Channel Prior (DCP) with statistically determined parameters (DCPS), and a combination of DCPS with the CLAHE method (Contrast Limited Adaptive Histogram Equalization). The offered methods of digital virtual reconstruction of works of art are based exclusively on a scientific campaign; they use only the data that is available as initial data (the image itself is a subject for restoration). Therefore, they are free from the human factor, because of which, changes in the restored image can be madesubjectively. If there is no preserved true image of the restored object, then, no doubt, the adequacy of the reconstruction to the original can be considered only suppositive. Of course, one should keep in mind that the use of any technology, including digital, must be done with an understanding of the basic principles of their work. The methods we proposed, together with other studies (X-rays and ultraviolet), can be very useful to specialists in restoration. Such an expansion of the capabilities will allow the restorer to work on the natural object, taking into account both the considerations of a prioriinformation and his practical experience in order to carry out the required reconstructionmore correctly. The presented results indicate a significant increase in the quality of digital images (increase of informativeness), which can serve as an auxiliary tool for restorers when refining the algorithm of their actions.

Key words: restoration, interpolation, retouching and restoration of images, increasing the discernibility of small details.
