摘要
视皮层假体的研究对眼科医学具有重要的意义;设计了一种视皮层假体的结构,提出了一种基于视觉机理的图像信息编码策略;实际图像的仿真结果表明,本方法在保证图像质量的前提下,能采用更少的神经元来表征自然图像中的重要信息,为减少植入皮层刺激电极的数量提供了理论参考。
The research on Visual Cortex Prosthesis has a very important meaning in ophthalmology. A Visual Cortex Prosthesis structure is designed, and also an image information coding based on visual mechanism is pro- posed. The simulation results of the actual image show that this method can not only guarantee the image quality, but also can make people use fewer neurons to represent the important information in natural images, so that it can provide a theoretical reference to the reducing of the number of the implant cortex stimulation electrodes.
