User guided 3D scene enrichment

Enriching 3D scenes with small objects is an important step for creating realistic scenes. It becomes tougher to involve user guidance to increase the variety of the scene enrichment results. To resolve this problem, we present a user-guided 3D indoor scene enrichment framework that helps users to effectively apply their rules for small-object arrangements. The enrichment problem can be divided into three parts: what categories of small objects should appear, where the small objects should be placed and how to arrange them on furniture objects. The first two questions are answered by statistical information learned from image datasets and the third question is answered by constructing a cost function considering both constraints proposed by our system and arrangement rules specified by users. Our experiments show that this framework can efficiently generate plausible scene enrichments that conform to the user-specified arrangement rules.
