利用子波变换模拟人眼视觉信息提取过程的研究

The Research of Simulating Visual Information Abstracting by Wavelet Transform

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。

can be simulated by the wavelet transform with DOG wavelets.It is suspicion that there are multifrequency channels in the human vision system in this paper.The channel model that has feedback link and its bandwidth and central frequency is adjustable presented and discussed.
