Footnote 14: Generating a textual description from an image alone would be a very difficult problem in artificial intelligence, since it would require the solution of both the "vision problem" of how to extract the semantics of an arbitrary image and the top-down version of the "natural language problem," how to generate sentences from arbitrary semantics. The text-generating problem here is, fortunately, easier.
