Statistical models of appearance for eye tracking and eye-blink detection and measurement

Ioana Bacivarov, Mircea Ionita, Peter Corcoran
2008 IEEE transactions on consumer electronics  
A statistical Active Appearance Model (AAM) is developed to track and detect eye blinking. The model has been designed to be robust to variations of head pose or gaze.  ...  This global model is further extended using a series of sub-models to enable independent modeling and tracking of the two eye regions.  ...  In summary, traditional image-based eye tracking approaches track the eyes and detect eventual blinking by exploiting the differences between frames and making use of special characteristics of the eye  ...

Rendering refraction and reflection of eyeglasses for synthetic eye tracker images [article]

Thomas C. Kübler and Tobias Rittig and Judith Ungewiss and Christina Krauss and Enkelejda Kasneci
2015 arXiv   pre-print
While for the evaluation of robustness of eye tracking algorithms the use of real-world data is essential, there are many applications where simulated, synthetic eye images are of advantage.  ...  We show how a polynomial function fitting calibration performs equally well with and without eyeglasses, and how a geometrical eye model behaves when exposed to glasses.  ...  This will have an effect on detection rate and accuracy. Figure 1 : 1 Rendered image of an eye with a coated lens of -1 diopters.  ...
