C2RMF 使用多光谱 CRISATEL 相机扫描了多个博物馆中保存的一百幅画作 [3]。这些高分辨率图像不仅使我们能够在任何选定的光源下生成准确的彩色图像，而且还使我们能够重建每个像素的反射光谱。此类图像可用于对艺术作品进行视觉定性以及基于测量的定量科学分析。已经开发了几种图像处理工具来允许我们执行这些分析。 IIPImage 系统 [2] 使我们能够可视化高分辨率多光谱 16 位图像，查看颜色或每个光谱通道的图像细节，并叠加和比较不同的波长。互补查看系统使用创新的 3D 图形硬件加速查看器，使我们能够动态重建最终的颜色，同时交互式地改变光谱。该系统还允许我们执行分割、查看特定颜色空间的颜色分布以及执行动态光谱重建。
One hundred paintings conserved in several museums have been scanned by the C2RMF using the multi-spectral CRISATEL camera [3]. These high resolution images allow us to not only generate an accurate colour image under any chosen illuminant, but also allow us to reconstruct the reflectance spectra at each pixel. Such images can be used for a visual qualitative as well as measurement-based quantitative scientific analysis of the work of art. Several image processing tools have been developped to allow us to perform these analyses. The IIPImage system [2] enables us to visualize high resolution multi-spectral 16 bit images, view image details in colour or for each spectral channel and to super-impose and compare different wavelengths. A complementary viewing system uses an innovative 3D graphics hardware-accelerated viewer to allow us to reconstruct the resulting colour dynamically while interactively changing the light spectrum. The system also allows us to perform segmentation, view the colour distribution for a particular colour-space and perfonn dynamic spectral reconstruction.
