项目摘要

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".

早期视觉过程的研究大多关注于沿视觉通路运作的感受野的特性。然而，每个层次的视觉加工的属性不是独立的，而是对更高层次的加工具有累积效应。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学的指标，而不是生理学指标，将澄清信息在整合过程中的转换和处理的性质。在本研究中，我们利用信号检测理论中的统计效率作为指标。我们的目的是计算视觉加工的效率，特别是立体视觉和从运动中恢复的三维结构，从而阐明更高的整合过程的机制。然而，由于对称结构是视觉场景的基本结构之一，因此推导是基于对立体视的灵敏度测量，特别是对三维对称的灵敏度。此外，我们还需要研究空间视觉中的线性。研究结果在以下论文中有部分总结：“三维镜像对称的检测”、“二维和三维全局对称中不对称噪声的处理”和“赫尔曼网格上虚幻斜线的定向”。
