We used anti-correlated stimuli to compare the correspondence problem in stereo and motion. Subjects performed a two-interval forced-choice disparity/motion direction discrimination task for different displacements. For anti-correlated 1d band-pass noise, we found weak reversed depth and motion. With 2d anti-correlated stimuli, stereo performance was impaired, but the perception of reversed motion was enhanced. We can explain the main features of our data in terms of channels tuned to different spatial frequencies and orientation. We suggest that a key difference between the solution of the correspondence problem by the motion and stereo systems concerns the integration of information at different orientations.
我们使用反相关刺激来比较立体视觉和运动中的对应问题。受试者针对不同的位移执行双间隔强迫选择视差/运动方向辨别任务。对于反相关的一维带通噪声，我们发现了微弱的反向深度和运动。对于二维反相关刺激，立体视觉表现受损，但反向运动的感知增强。我们可以根据调谐到不同空间频率和方向的通道来解释我们数据的主要特征。我们认为，运动和立体视觉系统解决对应问题的一个关键区别在于不同方向信息的整合。
