Abstract

Visual scenes are often populated by densely layered and complex patterns of motion. The problem of motion parsing is to break down these patterns into simpler components that are meaningful for perception and action. Psychophysical evidence suggests that the brain decomposes motion patterns into a hierarchy of relative motion vectors. Recent computational models have shed light on the algorithmic and neural basis of this parsing strategy. We review these models and the experiments that were designed to test their predictions. Zooming out, we argue that hierarchical motion perception is a tractable model system for understanding how aspects of high-level cognition such as compositionality may be implemented in neural circuitry.

视觉运动感知的层次向量分析。
视觉场景通常由密集的层次和复杂的运动模式填充。动作解析的问题是将这些模式分解成对感知和动作有意义的更简单的组件。心理物理证据表明,大脑将运动模式分解为相对运动向量的层次结构。最近的计算模型揭示了这种解析策略的算法和神经基础。我们回顾了这些模型以及为验证其预测而设计的实验。缩小范围,我们认为层次运动感知是一个易于处理的模型系统,用于理解高级认知(如组合性)如何在神经回路中实现。

期刊介绍: The Annual Review of Vision Science reviews progress in the visual sciences, a cross-cutting set of disciplines which intersect psychology, neuroscience, computer science, cell biology and genetics, and clinical medicine. The journal covers a broad range of topics and techniques, including optics, retina, central visual processing, visual perception, eye movements, visual development, vision models, computer vision, and the mechanisms of visual disease, dysfunction, and sight restoration. The study of vision is central to progress in many areas of science, and this new journal will explore and expose the connections that link it to biology, behavior, computation, engineering, and medicine.
