| summary |
Various new imaging techniques have been used at the C2RMF, in order to digitize paintings and objects. These techniques are used for extensive and detailed non-destructive analysis of works of art in different ways and include multispectral imaging, panoramic viewing of objects, 3D laser scanning of painting surfaces and 3D photogrametric modeling of objects. These techniques are valuable tools in the restoration and conservation arsenal, allowing us to perform regular and accurate monitoring of works of art, to measure their conservation state and compare these with previous analyses. These techniques, however, result in huge quantities of data, which needs to be visualized and disseminated in several ways. The resulting images must also be accessible to various partners around the world via the Internet, but the data needs to be protected and the vast data sizes involved require careful handling and management. This paper describes several new developments that have been made at the C2RMF by our team in order to make extremely high resolution images available on line. We will examine as a case study the use, the manipulation and the share of high resolution colorimetric images between members of the museum research community. The system that has been developed is a light-weight client-server architecture that efficiently streams image data to the client, allowing the user to quickly view very large images even over a slow Internet connection. These developments have been released as Open Source software in the IIPImage project. |
