This paper discusses some problems that should be addressed by future object recognition systems.

In particular, there are things that we know how to do today, for example:

  1. Computing the pose of a free-form three-dimensional object from its outline (e.g. [106]).

  2. Identifying a polyhedral object from point and line features found in an image (e.g., [46, 89]).

  3. Recognizing a solid of revolution from its outline (e.g., [59]).

  4. Identifying a face with a fixed pose in a photograph (e.g., [10, 111]).
