Lossless compression of eye movement signals.

Compression of digital signals is widely employed in several areas such as speech signals. Concerning biomedical signals almost merely ECG signals have so far been compressed, in fact, in very many applications. To our knowledge, this compression study is the first one presented in the case of eye movement signal which are investigated in several medical specialties. In this study eye movements are electro-oculographically recorded. Tests performed to signals of patients of an equilibrium laboratory gave compression ratios generated with essential lossless compression methods.
