Natural Image Database

This image database provides a data set of calibrated images of natural scenes, including spectral information of scene illumination.

  • [1] All images are RGB color data in 8bit for each channel,
         where the data with pixel value more than 225 are much reliable.
  • [2] The spectral-power distribution of ambient light at image acquisition is attached to every image.
  • [3] The spectral-sensitivity functions of the camera used are provided.

*Notice Please state clearly use of this natural image database in your papers on the image data.
