Spectral videos are seven channel videos captured over the wavelength range of 380-1000 nm. Spectral images are 51 channel still images in the range of 450-950 nm. Unfavorable conditions, such as eyewear reflections, extreme angles and make-up were incorporated. One 51 channel images is about 140 MB in size and it is available in a form of 51 TIFF images. One seven channel image is about 20 MB available as a seven channel MATLAB matrix. On average, one spectral video contains about 80 frames giving a total of approximately 14,400 images. Each video is about 5 s long resulting in a size of about 1,6 GB on average. Per subject about 9,8 GB of data was collected that gives a total of about 293 GB.<\/p>\n\n\n\n<p>The associated journal article for the data is <a href=\"http:\/\/dl.acm.org\/citation.cfm?id=2968335\" target=\"_blank\" rel=\"noreferrer noopener\">SPEED: SPectral Eye vidEo Database<\/a> where the data acquisition process is described in detail.
