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

大多数关于早期视觉加工的研究都关注沿着视觉通路工作的感受野的特性。然而，视觉加工的每个水平中的属性并不是独立的，而是对更高的加工过程具有累积效应。这种情况在整合过程中尤其如此。因此，如果我们设计一些用于心理物理的指标，而不是生理指标，那么在整合过程中的信息转换和加工的性质就会被阐明。我们的目标是计算视觉处理的效率，特别是立体视觉和结构从运动中三维恢复的效率，从而阐明更高积分过程的机制。然而，由于对称结构是视觉场景中的基本结构之一，因此推导是基于对立体视觉的敏感性测量，特别是对三维对称性的敏感性。此外，我们还需要研究空间视觉中的线性度。这些结果在以下几篇论文中得到了部分总结：《三维镜对称的检测》、《二维和三维全局对称中非对称噪声的处理》和《Hermann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".
