摘要：作为经典的研究眼球运动的方法,眼电图(EOG)已经广泛地应用在多个领域。EOG信号中包含了不同类型的眼动信号和伪差,去噪和信号分离在EOG研究中一直备受关注。我们结合EOG信号的特点提出了一种新的基于WFMH的线性-非线性混合滤波器(简称为IWFMH)。仿真结果表明,该滤波器在保持信号边缘的同时能够更有效地除去噪声,EOG处理结果表明该滤波器在除去噪声的同时能够有效地分离出扫视和眨眼信号。
As a classic eye movement method, electrooculogram（EOG） has been extensively used in many applications. There are many different types of eye movements and artifact in the EOG signal. Noise attenuation and signal separation have received special attention in the EOG research. In this paper, we introduce a novel Linear-nonlinear combinational filter based on weighted FIR-median-hybrid （WFMH） with the characteristic of the EOG signal. The result of the simulation shows that this filter has the property of removing random noise more efficiently when preserving sharp edges. Finally, it is shown that the new filter is effective in separating saccadic and eye blink in the EOG signal.
