A Head Pose-free Approach for Appearance-based Gaze Estimation
نویسندگان
چکیده
(a) (b) (c) Figure 1: 2-D illustration of relationship between gaze direction and head pose. (a) Under a fixed head pose (r0, t0), gaze direction α can be estimated from appearance. (b) To obtain α under another head pose (r̂, t̂), the estimated α ′ should be corrected because of captured eye appearance distortion. (c) Under head pose (r̂, t̂), gaze direction under WCS should be further compensated for head rotation β .

An Incremental Learning Method for Unconstrained Gaze Estimation
This paper presents an online learning algorithm for appearancebased gaze estimation that allows free head movement in a casual desktop environment. Our method avoids the lengthy calibration stage using an incremental learning approach. Our system keeps running as a background process on the desktop PC and continuously updates the estimation parameters by taking user’s operations on the PC moni...
متن کاملActive Appearance Models for Gaze Estimation
This thesis describes the implementation of and the experimentation with a gaze estimation system based on an approach called the Active Appearance Model (AAM). Active Appearance Models are generative models of a certain visual phenomenon. They can be used to model specific patterns of variability in shape and grey-level appearance, which in turn can be used directly in image interpretation. Ou...
متن کاملMPIIGaze: Real-World Dataset and Deep Appearance-Based Gaze Estimation
Learning-based methods are believed to work well for unconstrained gaze estimation, i.e. gaze estimation from a monocular RGB camera without assumptions regarding user, environment, or camera. However, current gaze datasets were collected under laboratory conditions and methods were not evaluated across multiple datasets. Our work makes three contributions towards addressing these limitations. ...
