摘要
作者用光电池组装一个人工感受野，在一维上模拟视网膜神经节细胞的零交叉滤波特性；进一步用该人工感受野构建一个图像边缘检测系统，并成功地用该系统检测到图像边缘。与一般的基于视觉原理的图像系统相比，这种以人工感受野为基础的系统，在图像输入的同时即可并行地提取图像边缘信息，而更接近于动物视觉系统原型。此结果将为人工视觉和图像技术的发展提供新的探索。
Silicon photocells were used to make an artificial 1-D ganglion cell receptive field,characterized as a Zero-crossing filter. The artificial receptive field was further applied to construct the image system and had detected successfully image edge. Uulike general image system, based on artificial receptive field, this image system can extract edge information simultaneously when the image was being input. It was close to animal visual system. The results will be helpful to the developmeut of new artificial vision and image technology.
