Establishing a Baseline for Gaze-driven Authentication Performance in VR: A Breadth-First Investigation on a Very Large Dataset
Dillon Lohr, Michael J. Proulx, Oleg Komogortsev
This paper performs the crucial work of establishing a baseline for gaze-driven authentication performance to begin answering fundamental research questions using a very large data…
Temporal Persistence and Intercorrelation of Embeddings Learned by an End-to-End Deep Learning Eye Movement-driven Biometrics Pipeline
Mehedi Hasan Raju, Lee Friedman, Dillon J Lohr +1
What qualities make a feature useful for biometric performance? In prior research, pre-dating the advent of deep learning (DL) approaches to biometric analysis, a strong relationsh…
Eye Know You Too: A DenseNet Architecture for End-to-end Eye Movement Biometrics
Dillon Lohr, Oleg V Komogortsev
Eye movement biometrics (EMB) is a relatively recent behavioral biometric modality that may have the potential to become the primary authentication method in virtual- and augmented…
Hierarchical HMM for Eye Movement Classification
Ye Zhu, Yan Yan, Oleg Komogortsev
In this work, we tackle the problem of ternary eye movement classification, which aims to separate fixations, saccades and smooth pursuits from the raw eye positional data. The eff…
Benefits of temporal information for appearance-based gaze estimation
Cristina Palmero, Oleg V. Komogortsev, Sachin S. Talathi
State-of-the-art appearance-based gaze estimation methods, usually based on deep learning techniques, mainly rely on static features. However, temporal trace of eye gaze contains u…
OpenEDS2020: Open Eyes Dataset
Cristina Palmero, Abhishek Sharma, Karsten Behrendt +3
We present the second edition of OpenEDS dataset, OpenEDS2020, a novel dataset of eye-image sequences captured at a frame rate of 100 Hz under controlled illumination, using a virt…
Assessment of Shift-Invariant CNN Gaze Mappings for PS-OG Eye Movement Sensors
Henry K. Griffith, Dmytro Katrychuk, Oleg V. Komogortsev
Photosensor oculography (PS-OG) eye movement sensors offer desirable performance characteristics for integration within wireless head mounted devices (HMDs), including low power co…
Tertiary Eye Movement Classification by a Hybrid Algorithm
Samuel-Hunter Berndt, Douglas Kirkpatrick, Timothy Taviano +1
The proper classification of major eye movements, saccades, fixations, and smooth pursuits, remains essential to utilizing eye-tracking data. There is difficulty in separating out…
Custom Video-Oculography Device and Its Application to Fourth Purkinje Image Detection during Saccades
Evgeniy Abdulin, Lee Friedman, Oleg Komogortsev
We built a custom video-based eye-tracker that saves every video frame as a full resolution image (MJPEG). Images can be processed offline for the detection of ocular features, inc…
Method to Detect Eye Position Noise from Video-Oculography when Detection of Pupil or Corneal Reflection Position Fails
Evgeny Abdulin, Lee Friedman, Oleg V. Komogortsev
We present software to detect noise in eye position signals from video-based eye-tracking systems that depend on accurate pupil and corneal reflection position estimation. When suc…
Synthetic Database for Evaluation of General, Fundamental Biometric Principles
Lee Friedman, Oleg Komogortsev
We create synthetic biometric databases to study general, fundamental, biometric principles. First, we check the validity of the synthetic database design by comparing it to real d…
Photosensor Oculography: Survey and Parametric Analysis of Designs using Model-Based Simulation
Ioannis Rigas, Hayes Raffle, Oleg V. Komogortsev
This paper presents a renewed overview of photosensor oculography (PSOG), an eye-tracking technique based on the principle of using simple photosensors to measure the amount of ref…
Hybrid PS-V Technique: A Novel Sensor Fusion Approach for Fast Mobile Eye-Tracking with Sensor-Shift Aware Correction
Ioannis Rigas, Hayes Raffle, Oleg V. Komogortsev
This paper introduces and evaluates a hybrid technique that fuses efficiently the eye-tracking principles of photosensor oculography (PSOG) and video oculography (VOG). The main co…
A Study on the Extraction and Analysis of a Large Set of Eye Movement Features during Reading
Ioannis Rigas, Lee Friedman, Oleg Komogortsev
This work presents a study on the extraction and analysis of a set of 101 categories of eye movement features from three types of eye movement events: fixations, saccades, and post…
