ISET HDR Driving scene light groups

The dataset comprises 2000 driving scenes, each defined by four spectral radiance maps representing illumination by the sky, headlights, streetlights, and other light sources (e.g., tail lights, bicycle lights). In addition to the spectral data, the light groups include pixel level metadata of the objects, specifying object instances and depth maps. Instructions for reading the data and metadata are on the GitHub ReadMe and Wiki pages.

To simulate various lighting conditions, the four maps are combined with different weights. The ISETCam (https://github.com/ISET/isetcam/wiki) and isethdrsensor (https://github.com/ISET/isethdrsensor) GitHub repositories contain software to read the light groups and select the appropriate weights for achieving the desired dynamic range and low-light conditions.
