Generate or retrieve text descriptions/tags for images

This area consists of two methods for labelling images:

  • Automatically analyzing images, their context, and their metadata in order to provide a thorough and accurate description that is accessible to someone who cannot see the image. This may take the form of a text description or tag.
  • Additionally, this area may draw from the image tagging protocols used by popular sites such as Flickr, Facebook, and Google, and would benefit greatly if these sites were to converge on a single, standard tagging protocol.
