学生中心在实时眼动追踪方面跳了很多 [英] Pupil Center is Jumping a Lot in Real Time Eye Tracking
问题描述
在我的眼动跟踪项目中，瞳孔中心跳得很多，我不认为这是一个固定点.
In my eye tracking project, the pupil center is jumping a lot and I don't see it as a fixed point.
我该怎么办?
我的想法是将2帧中的瞳孔中心和瞳孔与阈值进行比较，但这并不能解决问题.另一点是相机噪音.
My idea is comparing the pupil center and pupil in 2 frames with a threshold but it doesn't help the problem. Another point is camera noise.
我该如何减少噪音?
我使用了 starburst算法.
Starburst :一种基于视频的眼睛跟踪的混合算法，结合了基于特征的方法和基于模型的方法.
Starburst: A hybrid algorithm for video-based eye tracking combining feature-based and model-based approaches.
推荐答案
上下文
关于眼动追踪技术的信息很少.但是，由于我在这个主题上花费的时间(不多)，因此提出了几个问题.一个与眼动跟踪库问题有关，而另一个与另一种情况有关类似的问题.如您所见，此主题不是直观且容易解决的问题.但是不要失去力量.
Context
Information regarding eye tracking technologies lacks a lot. However, due to the time (not much) that I am working on this topic, I am raising several issues. One was related to an eye tracking library issue, while the other was related to an alternative to a similar problem. As you can see, this topic is not intuitive and trivial to solve. But do not lose your strength.
被称为用于交互式应用程序的注视跟踪技术 [1]，本文可以回答您的疑问.本文介绍了眼动追踪技术，并重点介绍了可能促进其在一般应用中使用的最新进展.作者还介绍了瞳孔角膜反射技术 [2， 3]由于其声称的可用性优势，并且表明该方法仍不太适合一般的交互式应用程序.
Titled as Eye gaze tracking techniques for interactive applications [1], this paper could answer your doubts. The paper presents a review of eye-tracking technologies and focuses on recent advancements that might facilitate its use in general applications. The authors are also presenting a description of the pupil–corneal reflection technique [2, 3] due to its claimed usability advantages, and show that this method is still not quite appropriate for general interactive applications.
不过，对于您来说，使用眼动追踪技术阅读一些常规的可用性测试可能很重要.一篇很好的文章标题为 可用性测试中的眼睛跟踪 ，作者在其中描述了与相机校准有关的问题，这些问题是现实生活中使用的限制因素.另一方面，标题为
Still, it might be important for you to read some general Usability Testing within the use of eye-tracking technologies. One good article is the one titled as Eye-tracking in Usability Testing, where the author describes issues regarding the camera calibration to be the limiting factor for real-life use. On the same hand, the article titled as UXer’s quick guide to eye tracking describes and advice you how to use it.
也许谁会担心，在我们的项目中，我们开发了两个存储库.第一个名为 eye-tracker-setup 的存储库是首次尝试提取信息关于 Tobbi Eye Tracker 4C 设备.但是，我们并没有成功，因此创建了另一个名为 eye-tracker-naive .
Just who may concern, in our project we developed two repositories. The first repository called as eye-tracker-setup, was a first attempt to extract information regarding the Tobbi Eye Tracker 4C device. However, we did not succeed that much, so that created another repository called eye-tracker-naive.
