Observers judged the apparent signs and magnitudes of surface slant from monocular textured images of convex or concave dihedral angles with varying fields of view between 5 degrees C and 60 degrees C. The results revealed that increasing the field of view or the regularity of the surface texture produced large increases in the magnitude of the perceptual gain (i.e., the judged slant divided by the ground truth). Additional regression analyses also revealed that observers slant judgments were highly correlated with the range of texture densities (or spatial frequencies) in each display, which accounted for 96% of the variance among the different possible dihedral angles and fields of view.
观察者从具有5度至60度之间不同视野的凸面或凹面二面角的单眼纹理图像中判断表面倾斜的明显迹象和大小。结果表明，增加视野或表面纹理的规则性会使感知增益的大小大幅增加（即判断的倾斜度除以实际倾斜度）。额外的回归分析还表明，观察者的倾斜判断与每个显示器中纹理密度（或空间频率）的范围高度相关，这解释了不同可能的二面角和视野之间96%的方差。
