AI's capabilities are limited. They can with great accuracy identify leaf
types. A specialist could work onward from that. Consider this applied to
completely uncategorized images.

Mind you I am at a phase of proposing a task for ImageClef which is why I
have asked about this here. Examples I mentioned are to give an idea about
the capability of the current state of ImageClef contributors. What would
community want more as a goal of automated tagging?
