Many works on this subject have been proposed these recent years. They can mainly be decomposed into two groups: geometric methods and texture synthesis methods. Texture synthesis methods work best with images containing only textures while geometric approaches are limited to smooth images containing strong edges. In this paper, we first present an extended state of the art. Then a new algorithm dedicated to both types of images is introduced. The basic idea is to decompose the original image into a structure and a texture image. Each of them is then filled in with some extensions of one of the best methods from the literature. A comparison with some existing methods on different natural images shows the strength of the proposed approach.

By constantly increasing resolution and accuracy of our system we can enable the documentation of small deviations of even flat surfaces – like frescos. This enables documentation of important features for restoration like small fractures or topology of paintstrokes for scientific research. The 3D-documentation can be done in-situ, radiation-free and contact-free using a structured (coded) light-source and a digital camera. Using light for documentation of colourful painted surface lead to the integration of colour-filtering techniques to ”see thru” the first layer(s) of paint. This approach, typically known from photography, is used to reveal under- drawings of paintings. While photographs suffer from lens distortion lacking a precise scale, we can provide the height of paint-layers in µm in a properly calibrate...

With the help of this technology the museums’ artifacts and scientific projects can now be displayed for the visitors in a highly spectacular way, which not only educates, but also entertains the visitors. In spring 2011 The Museum of Fine Arts, Budapest started a comprehensive program ( Budapest Mummy Project ) for the interdisciplinary research of four mummified remains from the Egyptian Collection of the Museum of Fine Arts, Budapest. Beside Egyptological studies, the program also covered researches based on natural science and medical diagnostic techniques, such as CT-scanning, and also anthropological, chemical, and radiocarbon analyses. One particular question has interested people for a long time: what kind of secrets do the Ancient Egyptian mummies hide? With the help of modern medical diagnostic techniques...
