眼动信号处理方法的研究

The Studies on Eye-Movement Signal Processing

本文介绍了一种应用互相关分析法在客观视力测试时对眼动信号进行识别分类的计算方法.作者根据视动性眼震与视动性光靶互相关的原理,对眼动信号与光靶移动信号作互相关运算,以其互相关的结果来判别眼动类型.这种方法计算简单,信号处理速度快,且识别准确率很高,是目前最适合对眼动信号进行识别分类的算法.作者认为慢相速度互相关法明显优于快相频率互相关法.

In this paper, a correlative algorithm for discriminating eye-movement signal in objective measurement of visual acuity has been presented. Auther has calculated the correlation between eye-movement sig- nal and moving target signal according to optokinetic nystagmus correlated with optokinetic target, and based the discrimination for types of eye-movement upon the calculative results.This algorithm possesses simple Calcula- tion, fast signal processing velocity and accurate discrimination. Anther considers this algorithm is the fittest meth- od for distinguishing and classifying eye-movement signal, and the slow phase velocity correlation is better than the fast phase frequency correlation.
