摘要：Structural approaches of pattern recognition are frequently proposed for man-made objects in aerial images. Especially model based methods are considered using geometric, topologic and structural kno wled ge by means of polyhedral parametric or generic models. We review some aspects of perceptual grouping with respect to these recognition tasks. Emphasis is put on so me severe problems encountered in the application. No new results or methods are reported. Instead a qualitative compariso n and discussion is given between two such approaches with respect to these problems. Also the importance of associative access techniques is stressed
