Microsaccades are high-velocity fixational eye movements, with special roles in perception and cognition. The default microsaccade detection method is to determine when the smoothed eye velocity exceeds a threshold. We have developed a new method, Bayesian microsaccade detection (BMD), which performs inference based on a simple statistical model of eye positions. In this model, a hidden state v...

Video-based eye gaze detection systems are useful for eye-slaved support system for the severely disabled. The pupil center in the video image is a focal point to determine the eye gaze. Recently, to improve the disadvantages of traditional pupil detection methods, a pupil detection technique using two light sources (LEDs) and the image difference method was proposed [1]. In addition, for users...

This study proposes a general diagnostic approach based on a camera based eye-tracking technique and a discrete Kalman filter as an iris tracker. In an event driven scenario, the proposed iris-tracking method is used to locate and track the subject’s eye movement and gesture by comparing it to a set of classified normal and typical gestures. The database is based on available videos as well as ...

The task of face recognition has been actively researched in recent years , and many techniques have been proposed. This paper reports on the design, implementation and experimental study of an improved technique for face recognition, including eye detection in the preprocessing phase of a localized face image. After a brief summary of some known face recognition techniques, we present an innov...
