title	Computation-friendly shape grammars: Detailed by a sub-framework over parametric 2D rectangular shapes

summary	NP-hardness of parametric subshape recognition for an arbitrary number of open terms is proven. Guided by this understanding of the complexity of subshape recognition, a framework for computation-friendly parametric shape grammar interpreters is proposed, which is further detailed by a sub-framework over parametric two-dimensional rectangular shapes. As both the proof of NP-hardness and rectangular sub-framework invoke elements in graph theory, the relationship between shape and graph grammars is also explored.

title	Automatic Extraction of Building Features From Image Data: How Far Are We?
doi	https://doi.org/10.52842/conf.caadria.2009.727
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 727-736
summary	This paper examines how far we are towards automatic extraction of building features, by comparing two pipelines from image data to building features: an ideal pipeline, based on the requirements of an on-going project, and a realistic pipeline, based on current computer vision technologies.
