Appearance-based gaze estimation in 2-dimensional screen coordinates–the prediction of the users' gaze from webcam footage–cannot yet compete in accuracy with infrared (IR) eye trackers. Yet by circumventing the constraints of requiring dedicated hardware, it shows great potential in many ...
Revisiting Data Normalization for Appearance-Based Gaze Estimation - Max Planck Institute for Informatics 解决的问题 基于外观的视线估计方式中,头部姿态和相机拍摄距离的多样性不利于训练的收敛。前期工作通过将输入图像和视线映射到归一化空间,来消除这种三维空间中的多变性,但该种方法的有效性没有明确定论。 作者...
This evaluation provides clear insights and allows us to identify key research challenges of gaze estimation in the wild. 基于外观的视线估计算法在现实环境下能够良好的工作,但现有的数据集却是在有约束的实验室条件下收集的,很多检测方法也没有进行跨多个数据集评估。本文研究了室外环境下基于外观的视线估计...
本周的主要任务是利用cnn完成视线追踪模型的初步训练,根据论文Appearance-Based Gaze Estimation in the Wild中的实现方法(如下图),我们本周在未进行图像处理的前提下,通过将眼部图像直接喂入cnn进行了初步的训练。 训练采用的数据集为论文中提供的MPIIGaze数据集,在直接使用眼睛图像训练过程中只采用了数据集中左眼的数...
首先,论文作者分别建立人脸坐标系与摄像机坐标系,具体规则可参考Gaze Estimation笔记——data normalization。归一化主要通过透视变换,达到以下目标: 将摄像机视角从固定距离dd正对双眼位置tt; 将人脸坐标与摄像机坐标的xx轴平行。 归一化后的到分辨率固定的眼部图像ee与2维的头部转动角度向量hh。这样的归一化将跨数据集...
Refining Eye Synthetic Images via Coarse-to-Fine Adversarial Networks for Appearance-Based Gaze EstimationRecently, several models have achieved great success in terms of reducing the gap between synthetic and real image distributions with large unlabeled real data. However, collecting such large amounts...
Offset Calibration for Appearance-Based Gaze Estimation via Gaze Decomposition Zhaokang Chen Bertram E. Shi The Hong Kong University of Science and Technology zchenbc@connect.ust.hk eebert@ust.hk Abstract Appearance-based gaze estimation provides relatively unconst...

本篇博客是笔者在读完论文“It’s Written All Over Your Face:Full-Face Appearance-Based Gaze Estimation”后的一个小小总结。 该篇论文主要提出了一种基于完整脸部图像,通过加入了空间权重的CNN得到2D、3D视线方向的方法,并对完整脸部图片对于视线检测的作用进行了相关实验与分析。
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 useful information for estimating a given gaze point. For example, approaches leveraging sequential eye gaze information whe...
