Abstract

Stereoacuity thresholds measured on disparity pedestals are generally found to increase exponentially as the pedestals move away from horopters. However, Farell, Li, and McKee recently found that for sinusoidal stimuli this threshold function had a dip—a pedestal effect. This paper examines the underlying neural mechanism. We suggest a general disparity coding scheme with two position parameters, which are necessary to account for the phenomenon that the response of the energy model depends on the absolute phase of the stimulus. This scheme was implemented to simulate the responses, calculated from an energy model, of the neurons of a full V1 cortical column. To explain the stereo pedestal effect, we propose a decoding mechanism, which is first processed along the phase dimension and then along the orientation dimension. The final step of the decoding mechanism, probability summation over the outputs of spatial frequency channels, yields the dip, producing a disparity increment threshold function similar to the psychophysical result.

创新点

在立体视觉差基底上测量的敏度阈值一般是随着基底离开同视点而呈幂指数增长. 但 是法诺等人发现当使用正弦图象时阈值函数有一勺形凹陷 - 基底效应. 本文试图检查这一现象 下的神经机制. 我们提出了一个有两个参数的一般视差编码机制. 为了解释立体视觉的基底效应, 我们提出一种解码机制. 该机制使我们最后生成勺状的视差增值阈值函数.
