Spectral Scene Database: 2D multispectral scene data

High dynamic range spectral data are essential to accurately simulate the effects of optics and sensor. Using an appropriate and high quality initial data set is essential to accurately assess system performance.

The ISET package includes images from a collection of Multispectral high-dynamic range scenes (HDRS). Each scene is represented as a multidimensional array describing the spectral radiance (photons/sec/nm/sr/m2) at each pixel in the sampled scene. The spectral radiance image data are assumed to arise from a single image plane at a specified distance from the optics. The spectral power of the scene illuminant is included with each data file. ISET provides software tools to calculate spectral reflectances and change scene illumination.

Multispectral and hyperspectral image data can be downloaded from this and other websites. ISET provides scripts to illustrate how to read and create scene radiance data from the spectral image databases listed below.
