An estimation model of pupil size for 'Blink Artifact' and it's applications
نویسندگان
چکیده
It is well known that the measuring of pupil size is influenced by noises and blinking. This paper describes the development of an estimation model of pupil size for ’blink artifact’ which is based on a 3 layered perceptron with back propagation method. The model was trained by pupil responses with artificial blinks. It was found that pupil size during the blink period could be estimated according to the training period. When this model was applied to pupillary changes for subjects viewing TV programs, inappropriate power of frequencies were removed in the frequency analysis for temporal pupillary change. This result provides evidence that this model can remove faults from pupil response measurements.

Development of an Accommodation-Dependent Eye Model and Studying the Effects of Accommodation on Electron and Proton Dose Conversion Coefficients
Introduction International Commission on Radiological Protection (ICRP) has provided a comprehensive discussion on threshold dose for radiation-induced cataract in ICRP publication 116. Accordingly, various parts of the eye lens have different radio-sensitivities. Recently, some studies have been performed to develop a realistic eye model with the aim of providing accurate estimation of fluence...
متن کاملA Novel Semiblind Signal Extraction Approach for the Removal of Eye-Blink Artifact from EEGs
A novel blind signal extraction (BSE) scheme for the removal of eye-blink artifact from electroencephalogram (EEG) signals is proposed. In this method, in order to remove the artifact, the source extraction algorithm is provided with an estimation of the column of the mixing matrix corresponding to the point source eye-blink artifact. The eye-blink source is first extracted and then cleaned, ar...
متن کاملPupil size dynamics during fixation impact the accuracy and precision of video-based gaze estimation
Video-based eye tracking relies on locating pupil center to measure gaze positions. Although widely used, the technique is known to generate spurious gaze position shifts up to several degrees in visual angle because pupil centration can change without eye movement during pupil constriction or dilation. Since pupil size can fluctuate markedly from moment to moment, reflecting arousal state and ...
متن کاملCombining Blink, Pupil, and Response Time Measures in a Concealed Knowledge Test
The response time (RT) based Concealed Knowledge Test (CKT) has been shown to accurately detect participants' knowledge of mock-crime-related information. Tests based on ocular measures such as pupil-size and blink-rate have sometimes resulted in poor classification, or lacked detailed classification analyses. The present study examines the fitness of multiple pupil and blink related responses ...
متن کاملCapturing and evaluating blinks from video-based eyetrackers.
Blinks are related to several emotional states, and the present report describes a simple, reliable way to measure blinks from the video stream of an eye obtained during eyetracking, where the source of the eye video is a video camera attached to a head-mounted eyetracker. Computer vision techniques are employed to determine the moments that a blink starts and ends, for the purpose of calculati...
