Abstract

This paper discusses two new developments in methods for virtually reconstructing paintings that have been painted over from Xray synchrotron imaging data of their canvases. First, Xray synchrotron data often contains areas of information loss, in which signal from underlayers was unable to penetrate particularly thick or Xray- absorbent surface features. We present a new method for automatically identifying these areas so that they may be inpainted. Second, we present preliminary results in which we reconstruct the colors of the underpainting directly from the Xray synchrotron imaging data. This is to our knowledge the rst attempt at accurate color reconstruction from this type of data.
