The method builds on well-known Gestalt rules and, crucially, models their conjoint interactions rather than treating each rule in isolation. Applied to line drawings, it detects object groups and repeated elements following Gestalt principles, then summarizes them by displaying fewer repetitions or replacing them with simpler shapes. Results are demonstrated on architectural models of diverse styles, with potential extensions to other illustrations and 3D

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.  \nCR Categories: I.3.5 [Computer Graphics]: Geometric Modeling and Level of Detail—Geometric algorithms;  \nKeywords: simplification, abstraction, Gestalt  \nLinks: DL PDF  \n1 Introduction  \nArtistic imagery, architectural renderings, cartography and games often exploit abstraction to clarify, exaggerate, simplify or emphasize the visual content. Abstraction is a strategy for communicating information effectively. It allows artists to highlight specific visual information and thereby direct the viewer to important aspects of the structure and organization of the scene. In this paper, we present an approach to the abstraction of 2D shapes, in particular  \nACM Reference Format  \nNan, L. , Sharf, A. , Xie, K. , Wong, T. , Deussen, O. , Cohen-Or, D. , Chen, B. 2011.
