David Marr's approach to the study of vision has been tremendously influential. However, the approach proposes the goal of computing invariant shape descriptions from image-based information, a task that appears implausible, given the tremendous variation that can occur between images displaying a single object. Theorists in the field of three-dimensional object recognition have rejected the approach of computing object-centered representations, and instead propose representations of objects from the perspective of a viewer. If object-centered descriptions of objects exist in the brain, they are more likely to underlie motor interaction with objects rather than visual object understanding.
大卫·马尔研究视觉的方法极具影响力。然而,该方法提出了从基于图像的信息中计算不变形状描述的目标,鉴于显示单个物体的图像之间可能存在巨大差异,这一任务似乎不太可行。三维物体识别领域的理论家摒弃了计算以物体为中心的表征的方法,转而从观察者的角度提出物体的表征。如果大脑中存在以物体为中心的物体描述,那么它们更有可能是与物体进行运动交互的基础,而非视觉上对物体的理解。
