Description
The exr folder contains a high-resolution dataset, consisting of 30 hyperspectral images covering a wide spectral range.
The acquisitions have 31 channels in the range 420-720 nm, with a separation of 10 nm.
The spectral images are reflectance images, which are normalized by the intensity of the reference white of Spectralon (calibrated 99% reflectance).
Capture setup
- Camera: Pointgrey Grasshopper 9.1MP Monochromatic (GS3-U3-91S6M-C)
- Lens: Jenoptik UV-VIS-IR 60mm f/4 apochromatic lens
- Filters: Liquid Crystal Tunable Filters (VariSpec VIS 400-720)
- Light Source: Xenon Illumination (Thorlab HPLS-30-4)
How to read the files
An example MATLAB code for reading a hyperspectral EXR file is given in
example.m under code.
