Example of blink detection process. (a) VEOG and low-frequency approximations after wavelet transform; (b) threshold processing; (c) square waves; (d) blink-removed VEOG and separated voluntary blink. In blink vector, a value of is an involuntary blink, is a voluntary single blink, and is a voluntary double-blink.
