Properties of integrating process of information passed through visual processes for stereo and motion with use of efficiency index.

对早期视觉加工的研究主要集中在沿着视觉通路的感受野的特性上。然而，在视觉加工的每个级别的属性不是独立的，而是累积的影响更高的过程。在整合过程中尤其如此。因此，如果我们设计一些心理物理学的指标，而不是生理学的指标，那么整合过程中的信息转换和加工的性质将得到澄清。我们的目标是计算视觉加工的效率，特别是立体视觉和从运动中恢复三维结构的效率，从而阐明高级整合过程的机制，然而，推导是基于立体视觉的敏感性测量，特别是对三维对称性的敏感性，因为对称结构是视觉场景中的基本结构之一。此外，我们还需要研究空间视觉中的线性，其结果部分总结在以下论文中：“三维镜像对称性的检测”，“二维和三维全局对称性中的非对称噪声的处理”，以及“赫尔曼网格上虚幻斜线的定向”。

Most researches for early visual processes have been concerned with properties of receptive fields which operate along the visual pathway. However, the properties in each level of visual processing are not independent but have cumulative effects on higher processes. This is the case particularly in an integrating process. Thus, the properties of information transformation and processing in the integration process will be clarified if we devise some index used in the psychophysics, not the physiological index.In the present study, we utilize statistical efficiency in the signal detection theory as the index. We aimed to compute the efficiency of visual processing particularly for the stereopsis and the three dimensional recovery of structure from motion, then to clarify the mechanism of the higher integrating process.However, the derivation is based on a sensitivity measurement of the stereopsis, in particular, the sensitivity to three dimensional symmetry because the symmetry structure is one of fundamental structures in the visual scene. In addition, we are required to investigate linearity in the spatial vision.The results are partly summarized in following papers : "The detection of three dimensional mirror symmetry", "Processing of asymmetrical noise in two-and three-dimensional global symmetry", and "Orientation of illusory oblique lines on Hermann grids".
