摘要:

提出了一种空间信息的表示模型。它是基于模糊约束表示为模糊几何关系,可以分层结构。空间模板的概念被引入到捕捉的想法,相关的对象在二维空间。该表示模型用于指定模板对象的相对位置和方向中的不精确或模糊信息。它示出了在本文中如何由该模型所表示的模板可以匹配对一个脆的情况下,识别该模板的一个特定的实例。此外,计算实例与模板之间的接近度(模糊度量)-该度量可以被解释为相似度。在这种情况下,模板识别可以被视为模糊模式识别的情况。这项工作的结果已经实施,并应用于一个复杂的军事问题,这项工作起源。

英文摘要:

A model to represent spatial information is presented in this paper. It is based on fuzzy constraints represented as fuzzy geometric relations that can be hierarchically structured. The concept of spatial template is introduced to capture the idea of interrelated objects in two-dimensional space. The representation model is used to specify imprecise or vague information consisting in relative locations and orientations of template objects. It is shown in this paper how a template represented by this model can be matched against a crisp situation to recognize a particular instance of this template. Furthermore, the proximity measure (fuzzy measure) between the instance and the template is worked out - this measure can be interpreted as a degree of similarity. In this context, template recognition can be viewed as a case of fuzzy pattern recognition. The results of this work have been implemented and applied to a complex military problem from which this work originated.
