| 摘 要： | 由于人类视觉系统在对图象信息进行初级加工过程中表现出由粗到细且能使其局域化的特性,而子波变换恰恰正好具有这样的特性.本文提出了利用DOG函数作为子波基函数,模拟人眼视觉信息提取过程,并给出了两维模拟计算的结果.提出了基于子波变换理论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.

| Abstract: | Because of the image information processing of the human vision system has the properties of the spatial scale analysis from coarse to fine and localization,and the wavelet transform has also the same properties.It is indicated that visual information can be simulated by the wavelet transform with DOG wavelets.Two-dimension simulation calculating result is given in this paper.The channel model of visual information abstracting with DOG wavelets is presented and discussed. |

| Keywords: | Wavelet transform DOG function Channel model of visual information abstracting |
