Image systems simulation must begin with an accurate description of the scene spectral radiance in radiometric units. ISET includes many synthetic and natural examples of such scenes.
Furthermore, for thorough systems analysis it can be important to include a representation of the space varying scene illumination and scene depth. These variables are part of the ISET scene representation, and it is possible to create many variations of a scene simply by editing its’ parameters.
More than 60 natural scenes can be downloaded from this online database. There are high dynamic range scenes as well as scenes that were measured well into the NIR.
ISET software creates synthetic target scenes that are used for industry standard and customized image quality metrics, including targets specialized for estimating color reproduction accuracy and spatial acuity.
