论文摘要
传统的室内场景合成方法通常采用两步方法:对象选择和对象排列。当前的最新对象选择方法基于卷积神经网络(CNN),可以为单个房间生成现实的场景。但是,它们不能直接扩展到合成具有不同功能的多个房间的样式兼容场景。为了解决此问题,我们将对象选择问题视为基于标签LDA(L-LDA)模型的组合优化。我们首先根据主题模型计算对象类别的发生概率分布,然后考虑其功能多样性以及样式兼容性的每个类别的对象,而不仅仅是单独的房间,而且还涉及房间之间的关联。用户研究表明,我们的方法通过将多功能和多房间设置与样式限制结合在一起,超过了基线,有时甚至会产生与专业设计师生产的场景相当的合理场景。
Traditional indoor scene synthesis methods often take a two-step approach: object selection and object arrangement. Current state-of-the-art object selection approaches are based on convolutional neural networks (CNNs) and can produce realistic scenes for a single room. However, they cannot be directly extended to synthesize style-compatible scenes for multiple rooms with different functions. To address this issue, we treat the object selection problem as combinatorial optimization based on a Labeled LDA (L-LDA) model. We first calculate occurrence probability distribution of object categories according to a topic model, and then sample objects from each category considering their function diversity along with style compatibility, while regarding not only separate rooms, but also associations among rooms. User study shows that our method outperforms the baselines by incorporating multi-function and multi-room settings with style constraints, and sometimes even produces plausible scenes comparable to those produced by professional designers.
