Dataset Description

     This dataset contains 59-band visible-NIR hyperspectral images from 420nm to 1000nm at 10nm intervals. The images were captured using a monochrome camera and two VariSpec tunable filters, VIS for 420-650nm and SNIR for 650-1000nm, for capturing each hyperspectral image. The hyperspectral image was then converted into a form of spectral reflectance by a calibration process using a colorchecker whose spectral reflectance property is known. The dataset is available only for research purpose and you may not redistribute the dataset.



  • The dataset contains 59-band hyperspectral images, including both visible and near-ifrared (NIR) domains, of colorful objects with rich textures, and therefore, is useful for the evaluation of various RGB-NIR/hyperspectral imaging and image restoration tasks.
  • The dataset is caliblated using a colorchart and saved in the spectral reflectance form. Therefore, users can simulate RGB-NIR/hyperspectral imaging pipeline with arbitrary camera sensitivity and illumination. Please see the sample code to do so.

Sample Code

[Sample Code]

     This is the sample code of basic implementation of the RGB-NIR imaging pipeliene. The code first converts the 59-band hyperspectral data to a camera RGB-NIR image, given camera spectral sensitivity. Then, the camera RGB-NIR image is transformed to the target color space by color correction using spectral reflectance data of the SG chart. You can modify the code to simulate the image under arbitrary illumination and camera sensitivity, depending on your purpose.
