Summary:
the applicability of aspect graphs
- It is still unclear how to compute aspect graphs for general complex objects like articulated assemblies or composite curved objects. Some research towards this has been reported.
- Exact aspect graphs do not take account of which features can be extracted reliably from images.
Extracting ideal line drawings is still an open problem. Moreover, line drawings are partial scene representations.
Aspect graphs should be able to accommodate different features than edges (e.g. surfaces), which could be a better choice in some situations.
- The high number of views in an exact aspect graph makes efficient indexing problematic. It is crucial to reduce the size of aspect graphs, e.g. by organizing unique aspects into groups of similar aspects.
- The computational complexity of aspect graph algorithms is always high.
