Spectral Viewer

Tools dedicated for art analysis based on spectral images

Spectral Viewer is a C++ software available on Windows and MacOS. Based on OpenGL, it uses the computational power of the GPU in order to do all the colorimetrics computation and the visualization process. It uses a specific pyramidal data representation based on a Principal Component Analysis (PCA) of the original reflectance information. This data representation allow us to process and visualyze multi and hyper spectral images in very high resolution.
