![]() | Hansen, Charles D.; Henderson, Thomas C. | CAD-based 3-D object recognition | We propose an approach to 3-D object recognition using CAD-based geometry models for freeform surfaces. Geometry is modeled with rational B-splines by defining surface patches and then combining these into a volumetric model of the object. Characteristic features are then extracted from this model ... | Object recognition; Strategy trees; Geometric knowledge representation; Automatic feature selection | 1989 |

![]() | Hansen, Charles D.; Henderson, Thomas C. | CAGD-based computer vision | Three-dimensional model-based computer vision uses geometric models of objects and sensed data to recognize objects in a scene. Likewise, Computer Aided Geometric Design (CAGD) systems are used to interactively generate three-dimensional models during the design process. Despite this similarity, the... | Computer Aided Geometric Design (CAGD); CAD-based vision; Model based vision; Strategy trees; Geometric knowledge representation; Automatic feature selection | 1987 |
