Structural Descriptions using Feature Context
Christoph Rasche · 2002
Visual object representations are often thought of a xed set of rigid parts or features. We show in a computational study, using furniture objects depicted in line drawings, that another valuable source of structural information is feature context. Employing such context evaluation during feature extraction, leads to a rich object description by surfaces and silhouette structures. This redundant description is useful and necessary because the same object can display dieren t conspicuous features in dieren t settings. Category-specic features are loosely expressed in order to match the structural variability existent within categories.
