VIRTUAL RESTORATION OF STONE INSCRIPTIONS BASED ON IMAGE ENHANCEMENT AND EDGE DETECTION

Abstract. A method of virtual restoration of inscribed texts is proposed for blurred inscriptions. Firstly, the image enhancement method is used to enhance the image of the current topos, and the optimal method is selected to highlight the text information. Secondly, the extracted text outline is extracted from the enhanced image, and the extracted text outline is partially processed to obtain a smooth outline, and finally the fill function is used to fill the text outline to complete the virtual restoration of the inscribed text. The experimental results prove that the method can restore for blurred text and retain the original stele text writing style. The results of this experiment can provide a reference basis for the virtual restoration of other inscriptions on the central axis.
