Fuzzy-based indoor scene modeling with differentiated examples

Abstract

Abstract Well-designed indoor scenes incorporate interior design knowledge, which has been an essential prior for most indoor scene modeling methods. However, the layout qualities of indoor scene datasets are often uneven, and most existing data-driven methods do not differentiate indoor scene examples in terms of quality. In this work, we aim to explore an approach that leverages datasets with differentiated indoor scene examples for indoor scene modeling. Our solution conducts subjective evaluations on lightweight datasets having various room configurations and furniture layouts, via pairwise comparisons based on fuzzy set theory. We also develop a system to use such examples to guide indoor scene modeling using user-specified objects. Specifically, we focus on object groups associated with certain human activities, and define room features to encode the relations between the position and direction of an object group and the room configuration. To perform indoor scene modeling, given an empty room, our system first assesses it in terms of the user-specified object groups, and then places associated objects in the room guided by the assessment results. A series of experimental results and comparisons to state-of-the-art indoor scene synthesis methods are presented to validate the usefulness and effectiveness of our approach.
