Ascender II, a Visual Framework for 3D Reconstruction
This paper presents interim results from an ongoing project on aerial image reconstruction. One important task in image interpretation is the process of understanding and identifying segments of an image. In this e ort a knowledge based vision system is being presented, where the selection of IU algorithms and the fusion of information provided by them is combined in an e cient way. In our current work, the knowledge base and control mechanism reasoning subsystem are independent of the knowledge sources visual subsystem. This gives the system the exibility to add or change knowledge sources with only minor changes in the reasoning subsystem. The reasoning subsystem is implemented using a set of Bayesian networks forming a hierarchical structure which allows an incremental classi cation of a region given enough time. Experiments with an initial implementation of the system focusing primarily on building reconstruction on three di erent data sets are presented.
