Median Filtering is Appropriate to Signals of Saccadic Eye Movements

In this paper we show nonlinear standard and hybrid median filters are appropriate to the filtering of signals of saccadic eye movements. Although these filters effectively attenuate noise, they do not harm the parameters of saccades, particularly the maximum velocity which is an important indicator of certain diseases and disorders in man. The filters have been tested by simulation as well as actual eye movement signals recorded electro-oculographically and photoelectrically.
