TAILIEUCHUNG - Make it Home: Automatic Optimization of Furniture Arrangement

Given the spatial relationships extracted as described above, our goal is to integrate this information into an optimization framework with a properly defined cost function quantifying the quality of the furniture arrangement. Given an arbitrary room layout populated by furniture objects, the synthesized arrangement should be useful for virtual environment modeling in games and movies, interior design software, and other applications. The search space of our problem is highly complex as objects are interdependent in the optimization process. The furniture positions and orientations depend on numerous factors, such as whether the object should be visible or accessible. It is very difficult to have a global optimization scheme or a closed-form solution. | Make it Home Automatic Optimization of Furniture Arrangement Lap-Fai Yu1 Sai-Kit Yeung1 Chi-Keung Tang2 Demetri Terzopoulos1 Tony F Chan2 Stanley J.

Abstract We present a system that automatically synthesizes indoor scenes realistically populated by a variety of furniture objects. Given examples of sensibly furnished indoor scenes our system extracts in advance hierarchical and spatial relationships for various furniture objects encoding them into priors associated with ergonomic factors such as visibility and accessibility which are assembled into a cost function whose optimization yields realistic furniture arrangements. To deal with the prohibitively large search space the cost function is optimized by simulated annealing using a Metropolis-Hastings state search step. We demonstrate that our system can synthesize multiple realistic furniture arrangements and through a perceptual study investigate whether there is a significant difference in the perceived functionality of the automatically synthesized results relative to furniture arrangements produced by human designers.
