人眼视觉信息处理模型的研究

The Stuty of Human Visual Information Processing Model

人造视网膜将外来光信号转化为电信号,用人造视网膜替代外层受损视网膜的功能,直接用人造视网膜处理之后的信号刺激视网膜内部神经细胞,从而使外部视网膜病变引起的失明得到恢复.而微电极之前的图像信息处理过程需要一个视觉信息处理模型为基础.该文利用子波变换对图像信息处理的灵活方便性,以及子波变换与人眼视觉信息处理过程的相一致性,在目前子波研究的基础上,把子波变换的思想应用于可恢复盲人视觉的视觉信息处理模型之中.

Artificial retina transforms the optical signal into electrical neuron through the microelectrode arrays. To substitute the na, by stimulating the inner retinal neuron directly with the artificial retina, the blindness obtains the recovery. Image signal, and stimulates the inner retinal artificial retina for the pathological retielectrical signals which be produced by information processing before the microelectrode arrays requires a suitable mathematical model for human visual information processing firstly. In this paper, a flexible and adjustable human visual information processing model is presented, which is based on the wavelet transform. With the flexible of wavelet transform to image information processing and the consistency to human visual information processing, the theory of wavelet transform is applied to human visual information processing for the recovery of the blind＇s vision.
