Irregular architectural layout synthesis with graphical inputs

- Statistical region merging and subgraph matching generate rasterized layouts and vector-based layouts respectively.
- The generated floor plans satisfy users' geometric and topological requirements.
- The generated layouts' appearance resembles the input image's graphic patterns.
- Architectural layout synthesis is promising beyond rectilinear rooms or Voronoi tessellations.

This paper presents a method for automatically constructing irregular floor plans. Given image patterns, the program produces a variety of layouts that satisfy users' geometric and topological requirements. The program extracts irregular regions from images via statistical region merging. It employs subgraph matching and simulated annealing to construct topologically feasible layouts. Methods for measuring similarities between the desired templates and irregular rooms are also reported. Applications using raster images and vector graphics are tested. Both applications generate feasible floor plans whose appearances resemble the input patterns. The results indicate that layout automation is valid without an orthogonal framework in the plane. Irregular layout synthesis allows architects to instantly implement visual preferences in early design stages.
