摘　　要：视网膜模型的建立是视网膜视觉假体中一个重要组成部分。视网膜模型是从已知的生理知识和实验数据出发模拟视网膜处理信息的功能,研究输入图像和输出神经冲动的关系。我们可以根据视网膜模型的原理将其分为硬件实现模型和算法模型。本文就对视网膜建模的国内外研究现状进行分析和讨论。Retinal model is an essential part in the retinal prosthesis. Based on the retinal physiology and the experimental data, the model is able to simulate the information processing in the retina, and can be used to investigate the relation between the input image and the neuron firing. We can categorize the models into circuit realization and algorithm realization. This article is a state-of-art review of different types of retinal models.
