本文提出了MetriCat，这是一种人类识别物体的能力模型，它既是一般类别的成员(例如“椅子”)，也是特定实例(“我的办公椅”)，以及视觉注意在这一能力中的作用。MetriCat以一种非线性的方式表示对象部件的属性及其关系，这为在类和实例级别进行识别提供了自然的基础(Stankiewicz&Hummel，1996)。与以前的结构描述模型(例如Hummel&Biederman，1992)一样，MetriCat独立地表示部件属性和关系，动态地将它们绑定到结构描述中。结果表明，视觉注意在形状识别中有两种作用：注意结合和注意信噪控制。MetriCat将这两个功能作为单个机制的特例来实现，用于控制代表不同对象部分的单元之间的同步关系。该模型考虑了班级的时间进程--以及实例。
This paper presents MetriCat, a model of the human capacity to recognize objects both as members of a general class (e.g. “chair”) and as specific instances (“my office chair”), and of the role of visual attention in this capacity. MetriCat represents the attributes of an object's parts and their relations in a non-linear fashion that provides a natural basis for recognition at both the class and instance levels (Stankiewicz & Hummel, 1996). Like previous structural description models (e.g. Hummel & Biederman, 1992), MetriCat represents part attributes and relations independently, dynamically binding them into structural descriptions. The resulting representation suggests two roles forvisual attention in shape recognition: attention for binding and attention for signal-to-noise control. MetriCat implements both functions as special cases of a single mechanism for controlling the synchrony relations among units representing separate object parts. The model accounts for the time course of class- and instanc...
