Digital Image Processing Techniques Applied to the Recovering and Conservation of the Graphical Heritage
چکیده
In this paper, we present several techniques of digital image processing that can be used in the recovering of damaged graphical documents. The ancient graphical documents give an important information in several subjects like history, ethnography or architecture reconstruction and then a good conservation and recovering is an important issue. The techniques presented are especially important when we try to recover ancient photographs or another ancient graphical documents. The materials used in these ancient graphical documents are degraded when time passes and a digital processing and storage allows a good conservation and a fast recovering process. We show techniques for recovering degraded illumination patterns and for recovering lost information due to the presence of degraded points into the image. The results show that these methods are well suited for the desired objective.
