Using filtered, broad band, fractal noise images we measured the dependence of D(min) and D(max) for stereo on luminance spatial frequency. D(min) was found to exhibit a simple dependence on the highest spatial frequency contained in the stimulus. D(max) depended on both image size and spatial frequency in a way that suggests an informational limit. Different rules govern D(min) and D(max) even for first order stereopsis, arguing against a common neural explanation based on independent access to the most pertinent spatial filter.
我们使用经过滤波的宽带分形噪声图像，测量了立体视觉中D（最小值）和D（最大值）对亮度空间频率的依赖性。结果发现，D（最小值）对刺激中包含的最高空间频率呈现出简单的依赖性。D（最大值）对图像大小和空间频率的依赖方式表明存在信息限制。即使对于一阶立体视觉，D（最小值）和D（最大值）也受不同规则支配，这与基于独立访问最相关空间滤波器的常见神经学解释相悖。
