DESCRIPTION
During this panel presentation information was shared on a collaborative project between the Yale University Art Gallery and the Yale CS department. Staff established that significant imaging data potentially crucial to the work of restoring damaged paintings, could be improved by leveraging the combined strengths of multiple modalities. we therefore aimed to undertake a collaborative exploratory project, with the assistance of Post-Doc students in the Computing and the Arts department of Computer Science at Yale, to design new software that would allow these modalities to be used together. For further information contact the presenter.TRANSCRIPT

3D ModelsHyper3D can read the following three-dimensional file formats:• Wavefront OBJ (.obj)• Polygon File Format (.ply)• Virtual Reality Modeling Language (.wrl)
2D Files• High dynamic ramge (.exr)• Portable Network Graphics (.png)• Bitmap (.bmp)• Joint Photographic Experts Group (.jpg)• DICOM: CT data (.dcm)
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 plotwidget 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
(a) shows the basic toolbar interface for convenient access to functions. (b) widgets for controlling the intensity of key/fill virtual lights. (c) CT medical imaging data navigation options of stack and volume rendering.
Medical ImagingHyper3D is capable of opening medical images that are compliant with the Digital Imaging and Communications in Medicine (DICOM) standard.
