Modeling Corneal Surfaces With Rational Functions for High-Speed Videokeratoscopy Data Compression

High-speed videokeratoscopy is an emerging technique that enables study of the corneal surface and tear-film dynamics. Unlike its static predecessor, this new technique results in a very large amount of digital data for which storage needs become significant. We aimed to design a compression techniq...
