Luminance spatial scale and local stereo-sensitivity

AbstractUsing filtered, broad band, fractal noise images we measured the dependence of Dmin and Dmax for stereo on luminance spatial frequency. Dmin was found to exhibit a simple dependence on the highest spatial frequency contained in the stimulus. Dmax depended on both image size and spatial frequency in a way that suggests an informational limit. Different rules govern Dmin and Dmax even for first order stereopsis, arguing against a common neural explanation based on independent access to the most pertinent spatial filter
