In recent years the study of spatial vision seems to have come almost full circle. Localized stimuli (such as lines, bars, and edges) were abandoned in favor of textured patterns (such as sinusoidal gratings), a trend that was accelerated by the discovery that gratings of sufficiently different spatial frequencies or orientations (stimuli localized in the Fourier domain) were detected independently. This led to various attempts to model form vision in terms of spatial frequency analysis. More recently there has been a shift toward models that include, once again, the local aspects of spatial processing; this trend is more consistent with both retinal and cortical physiology. (Still surviving is the notion of a complete set of orthonormal basis functions, but not sinusoidal ones.) Other important developments include attempts to model spatiotemporal interaction, and the discovery that spatial processing takes on an entirely different character in the absence of any temporal variation (i.e., when the retinal image is stabilized). We attempt to trace these developments in terms of a selected group of representative studies, which we examine in some depth.
近年来，空间视觉的研究似乎几乎又回到了原点。局部刺激（如线条、条纹和边缘）被摒弃，转而青睐纹理图案（如正弦光栅），这一趋势因以下发现而加速：足够不同空间频率或方向的光栅（在傅里叶域中局部化的刺激）是被独立检测的。这引发了各种根据空间频率分析对形状视觉进行建模的尝试。最近，又出现了一种向再次纳入空间处理局部方面的模型转变的趋势；这种趋势与视网膜和皮层生理学更为一致。（一组完整的正交基函数的概念仍然存在，但不是正弦基函数。）其他重要进展包括对时空相互作用建模的尝试，以及发现空间处理在没有任何时间变化时（即当视网膜图像稳定时）会呈现出完全不同的特征。我们试图根据一组选定的代表性研究来追溯这些进展，并对其进行深入研究。
