Current Video-Oculography (VOG) permits multidimensional, drift-free, non-
invasive measurement of eye movements, but cannot be used for fine recording
of fast eye movements (saccades), which would require high spatial and high
temporal resolutions, corresponding to global data rates in the range of 300Mb/s
A new technique is proposed for achieving high accuracy using very
low spatial frequency sampling and reconstructing a high-resolution binary
image of the pupil from a low-resolution grey-level frame, acquired with a
A recursive fitting algorithm for eye position detection is also
introduced, allowing correct measurements also when the pupil contour is only
