Generation process for the reconstruction of space curves

摘要

A two-step sequential interpretation model consisting of a generation process followed by a decision process is proposed to interpret a line drawing. The notion of a generation process is defined and illustrated by examples. Our specific interest here is the proposal of a particular generation process, and much of the discussion focusses in this. The decision process is suggested as a second independent phase to select a ‘most plausible’ interpretation based on some auxilliary criterion from among those provided by the generation process as consistent with the visual data S. Issues of implementation are also discussed.
