I've been doing some background reading on demosaicing raw images. I've seen the Kodak PhotoCD raw image dataset mentioned in a few papers on demosaicing:

After some googling, I haven't been able to find the Kodak dataset. Where can I download the Kodak PhotoCD dataset?

    $\begingroup$ If everything else fails, you can always ask the authors of the papers for the dataset they used. You have to be able to reproduce their results, and for that you need the dataset :) $\endgroup$ – penelope Oct 24 '12 at 20:03

The dataset appears to be in the public domain, and has been posted at this site here.

The pictures (24 in total) were originally released in 1991 on a CD. The original media with the actual image data could be requested via interlibrary loan; here is a WorldCat link to the repositories holding this item. The CD was originally distributed by Apple Computer. The raw version of the files do not appear to be available online.

  • $\begingroup$ The PhotoCD images seem to be a benchmark for demosaicing raw images. Images that have not yet been demosaiced do not really have color...there's just one channel (instead of 3 channels) per pixel. However, the images on r0k.us/graphics/kodak have already been processed into multi-channel color images. Can anyone help me to find the completely raw version of the Kodak PhotoCD images? $\endgroup$ – solvingPuzzles Oct 24 '12 at 0:46
  • $\begingroup$ @solvingPuzzles: I believe that the completely raw version of the Kodak PhotoCD images are on the actual disk. You might have to request it from another academic institution library. $\endgroup$ – Nicholas Kinar Oct 24 '12 at 1:38
  • $\begingroup$ Sounds good. I just requested the PhotoCD on interlibrary loan. Once I get the data, I'll post it online (I doubt Kodak will come after me for this...). $\endgroup$ – solvingPuzzles Oct 24 '12 at 1:54

RAW images do show color. Is green due to the double number of green cells of other basic components (RGB) having a Bayer filter or similar. It is on that where you have to apply the demosaicing algorithms to complete each color plane with values ​​in incomplete depending on their own neighbors pixels RAW image. nACHO (also looking those images)

  • $\begingroup$ It seems that the Kodak PhotoCD images were produced by scanning 35mm film. Hence the RAW images in this case should contain all three color channels. While extremely high-resolution scan can reveal the underlying film "grain", this is not the case here - so there should be no mosaic pattern whatsoever in the RAW images. $\endgroup$ – Boaz Arad Oct 2 '19 at 12:32
