Screenshot of the software with the two different example objects. Four different types of image data are loaded: (from the top left) a 3D scan model, CT 2D stack visualization, the color visualization of a multispectral image with eight spectral channels (the spectral plot widget on the right bottom illustrates the spectral reading of the red region), and volume rendering of the polychrome panel. The right-hand-side column shows the light controls for the 3D model/volume rendering visualization (key/fill light), CT stack data navigator and volume rendering options. At the bottom of the column, multispectral spectrum is scientifically visualized on the surface point followed by the mouse pointer.
Abstract
Art conservators now have access to a wide variety of digital imaging techniques to assist in examining and documenting physical works of art. Commonly used techniques include hyperspectral imaging, 3D scanning and medical CT imaging. However, most of the digital image data requires specialized software to view. The software is often associated with a particular type of acquisition device, and professional knowledge and experience is needed for each type of data. In addition, these software packages are often focused on particular applications (such as medicine or remote sensing) and are not designed to allow the free exploitation of these expensively acquired digital data. In this paper, we address two practical barriers in using the high-tech digital data in art conservation. First, there is the barrier of dealing with a wide variety of interfaces specialized for applications outside of art conservation. We provide an open-source software tool with a single intuitive user interface that can handle various types of 2/3D image data consistent with the needs of art conservation. Second, there is the barrier that previous software has been focused on a single data type. The software presented here is designed and structured to integrate various types of digital imaging data, including as yet unspecified data types, in an integrated environment. This provides conservators the free navigation of various imaging information and allows them to integrate the different types of imaging observations.
