Acquisitions: Drawings for Objects

Interpretation of line drawings of complex objects

The machine interpretation of line drawings (pioneered by Guzman’) has a privileged position in the computer vision literature. It has proved to be the inspiration and testing ground of important techniques of much wider application, such as discrete relaxation’. Ironically, the simplified and idealized nature of the line drawing interpretation problems studied, which make them so attractive as...

Recognition and Modeling of Architectural Objects from Architectural CAD Drawings

Recently in the eld of building CAD, research and development in CAD and data sharing among CAD tools has introduced object-oriented technology. This technology has brought object-oriented CAD tools that allow users to designing buildings by means of architectural objects and the standard data speci cation IFC (Industry Foundation Classes), which is involved in the architectural CALS (Commerce ...

Photographs of manipulable objects are named more quickly than the same objects depicted as line-drawings: Evidence that photographs engage embodiment more than line-drawings

Previous research has shown that photographs of manipulable objects (i.e., those that can be grasped for use with one hand) are named more quickly than non-manipulable objects when they have been matched for object familiarity and age of acquisition. The current study tested the hypothesis that the amount of visual detail present in object depictions moderates these "manipulability" effects on ...
