一、问题的提出国外很早就把电子技术应用于视觉研究中,国内也在开展这方面的工作。我们知道,自从Campbell等人,提出人的视觉系统的富氏频谱分析以来,视觉系统的空间频率理论和实验技术不断发展,他们根据心理物理实验及电生理实验结果,提出在视觉系统中存在着频率分析器,对图象进行富立叶频谱分析,由各个空间频率通道进行处理,然后进行综合的假说。Blakemore和Maffei则对双眼分别观看不同空间频率的条纹而产生的深度感知进行了观测,做出深度感知是皮层进行空间频率分析、综合的结果的假设。当然视觉
First, the issue raised Foreign long ago put electronic technology used in visual research, the country is also carrying out this work. We know that since Campbell et al. Proposed the Fourier spectrum analysis of the human visual system, the spatial frequency theory and experimental techniques of the visual system have been constantly evolving. According to the results of psychophysical and electrophysiological experiments, they are presented in the visual system Frequency analyzer, the image Fourier spectrum analysis, by the various spatial frequency channels for processing, and then make a comprehensive hypothesis. Blakemore and Maffei observed the depth perception of the two stripes viewing different spatial frequencies respectively, and made the assumption that depth perception is the result of the spatial frequency analysis of the cortex. Of course, vision
