Choose a more suitable indexed image archive

[davidfoerster]

Chromatik doesn't appear to be a reliable image index, because of the lack of support by its operator Exalead. Possible alternatives are:

• Flickr
  • well supported and reliable
  • only 16 colours available and multiple colours per query (undocumented, but available)
  • search by (visual) types and categories (undocumented, but available)
• Imagga multi-colour search
  • not yet available, but free access, as soon as testing begins
  • intelligent colour clustering
  • full RGB range, up to 5 weighted colours per query
  • can distinguish between foreground and background colours
• Picturelicious
  • requires self-hosting
  • only clandestine image archive use readily available
  • very simple indexing approach, no clustering
  • full RGB range and an arbitrary amount of colours per query
