基于格式塔的建筑物图画抽象

格式塔(Gestalt)理论总结了人类认知规则、模式和语义的若干规律,已有大量的研究针对独立的格式塔规则建立计算模型,但建立多个格式塔规则相互作用的耦合模型仍然是一个挑战.基于格式塔理论的若干主要规则建立了一个针对多个格式塔规则耦合的计算模型,并将该模型用于建筑物线画图的抽象;通过减少图画中重复结构元素的数目,或者将复杂的结构用简单结构替换的方式对建筑物结构进行概括和抽象.实验结果表明,该方法可以应用于风格各异的建筑物线画图,并可以扩展到其他类型的图画以及三维模型.

Conjoining Gestalt Rules for Abstraction of Architectural Drawings

We present a method for structural summarization and Abstraction of complex spatial arrangements found in architectural drawings.The method is based on the well-known Gestalt rules,which summarize how forms,patterns,and semantics are perceived by humans from bits and pieces of geometric information.Although defining a computational model for each rule alone has been extensively studied,modeling a conjoint of Gestalt rules remains a challenge.In this work,we develop a computational framework which models Gestalt rules and more importantly,their complex interactions.We apply conjoining rules to line drawings,to detect groups of objects and repetitions that conform to Gestalt principles.We summarize and Abstract such groups in ways that maintain structural semantics by displaying only a reduced number of repeated elements,or by replacing them with simpler shapes.We show an application of our method to line drawings of architectural models of various styles,and the potential of extending the technique to other computer-generated illustrations,and three-dimensional models.
