Roberts: machine perception of three-dimensional solids

What changed

Developed procedures for deriving structured descriptions of polyhedral three-dimensional objects from line drawings and photographs and for using those descriptions in scene analysis.

Scientific scope

The record is Roberts’s exact 1963 MIT doctoral thesis. Peter Elias is the documented thesis advisor, not a target-work author; later block-world vision systems, edge detectors and object-recognition methods remain separate.
