Overview of some of the relevant ICA-based methods for ocular and/or cardiac artifact removal in chronological order.

First author	Artifact	Electrode	Sample	Comment
Rong [65]	Ocular, cardiac	No	5	One of the first automated removal methods; requires a predetermined artifact template
Okada [66]	Ocular	Yes	7	Reliable performance for blinks occurring in rapid succession
Mantini [67]	Ocular, cardiac	No	12	Requires complex parameter tuning; can correct environmental artifacts
Dammers [68]	Ocular, cardiac	Yes	6	Uses signal amplitudes and phases; can correct for muscle artifacts
Klados [69]	Ocular	Yes	27	Hybrid regression-ICA approach; available as open source

Electrode: indicates whether an electrooculogram and/or electrocardiogram measurement is required. Sample: number of healthy volunteers used for validation.
