Completion of images of historical artifacts based on salient shapes

Protecting images of historical artifacts is of great value and cultural significance. In this study, we present a method for completing images of complex historical artifacts by referring to objects with similar shapes in other images. Our approach includes two fundamental stages. First, we reconstruct the salient shape of the damaged object using shape point set registration and curve fitting. Second, based on a shape guide map and gradients, we generate a new energy to complete damaged images of historical artifacts in terms of their shape and semantics. We obtained promising results with multiple images of historical artifacts, thereby demonstrating the superior performance of our proposed method compared with existing approaches.
