一种模拟人眼视觉信息提取过程模型的研究

The Research of A Simulating Visual Information Abstracting Model

本文提出利用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质疑，提出了一种基于子波变换理论，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。

can be simulated by the wavelet transform with DOG wavelets.It is suspicion that there are multi-frequency 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.
