提出了利用ＤＯＧ函数作为子波基函数，模拟人眼视觉信息提取过程。同时对普遍认为的视觉系统中存在着多个离散频率通道的观点提出了质疑，并提出了基于子波变换理论，具有反馈环节的中心频率和频带宽度可调的视觉信息提取通道模型。在文中讨论了这一模型的特点和潜在的应用前景。
The DOG function is proposed as a wavelet basis function to simulate human visual information extraction process. At the same time, it is questioned that there are many discrete frequency channels in the visual system, and a visual information extraction channel model based on the wavelet transform theory with adjustable feedback center frequency and bandwidth is proposed. In this paper, the characteristics and potential application of this model are discussed.
