在纹理三维表面的图像中,图案变化可以表征为方向和空间频率的变化,初级视觉皮层中的神经元对这些特征具有经典选择性。在此之前,我们已经证明,正确的3-D形状感知是视情况而定的方向流,运行平行于表面曲率的可见性。我们试图确定的相对贡献的方向调制(OM)和频率调制(FM)的检测从3-D表面的倾斜和形状。结果表明:1)当OM和FM指示的表面倾斜或曲率程度不一致时,即使FM指示的倾斜或曲率方向相反,但观察者的反应与OM指定的倾斜或曲率一致。2)对于倾斜表面,OM信息指示在浅倾斜和陡倾斜两者处的倾斜感知,而FM信息仅对陡倾斜有效。总之,这些结果表明OM信息在3-D倾斜和形状的感知中起主导作用。
In images of textured three-dimensional surfaces, pattern changes can be characterized as changes in orientation and spatial frequency, features for which neurons in primary visual cortex are classically selective. Previously, we have demonstrated that correct 3-D shape perception is contingent on the visibility of orientation flows that run parallel to the surface curvature. We sought to determine the relative contributions of orientation modulations (OMs) and frequency modulations (FMs) for the detection of slant and shape from 3-D surfaces. Results show that 1) when OM and FM indicate inconsistent degrees of surface slant or curvature, observer responses were consistent with the slant or curvature specified by OM even if the FM indicated a slant or curvature in the opposite direction to the same degree. 2) For slanted surfaces, OM information dictates slant perception at both shallow and steep slants while FM information is effective only for steep slants. Together these results point to a dominant role of OM information in the perception of 3-D slant and shape.
