物体的感知识别被概念化为这样一种过程，在该过程中，输入的图像在深凹区域被分割成诸如块、圆柱体、楔形和圆锥体的简单几何组件的排列。按分量识别理论的基本假设是，一组适度的广义圆锥分量，称为几何(N≤36)，可以从二维图像中的五个容易检测的边缘属性的对比中得到：曲率、共线、对称性、平行度和共终止。这些属性的检测通常在观看位置和图像质量上是不变的，因此当图像从新的视点投射或退化时允许稳健的对象感觉。因此，RBC对知觉组织的经典原则和模式识别之间迄今尚未确定的关系提供了原则性的解释：对规则化的约束(Pragnanz)表征的不是完整的对象，而是对象的组成部分。代表权来自于允许自由组合几何图形。分量恢复原理可以解释对象识别的主要现象：如果可以从输入中恢复两个或三个三角形的排列，即使对象被遮挡、新颖、深度旋转或严重退化，也可以快速识别。人类观察者对简单呈现的图片的感知实验结果为这一理论提供了经验支持。
The perceptual recognition of objects is conceptualized to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components, such as blocks, cylinders, wedges, and cones. The fundamental assumption of the proposed theory, recognition-by-components (RBC), is that a modest set of generalized-cone components, called geons (N≤ 36), can be derived from contrasts of five readily detectable properties of edges in a two-dimensional image: curvature, collinearity, symmetry, parallelism, and cotermination. The detection of these properties is generally invariant over viewing position and image quality and consequently allows robust object perception when the image is projected from a novel viewpoint or is degraded. RBC thus provides a principled account of the heretofore undecided relation between the classic principles of perceptual organization and pattern recognition: The constraints toward regularization (Pragnanz) characterize not the complete object but the object's components. Representational power derives from an allowance of free combinations of the geons. A Principle of Componential Recovery can account for the major phenomena of object recognition: If an arrangement of two or three geons can be recovered from the input, objects can be quickly recognized even when they are occluded, novel, rotated in depth, or extensively degraded. The results from experiments on the perception of briefly presented pictures by human observers provide empirical support for the theory.
