@jxncyym I'm having the same problem as you, can you tell me about your reproduction process?
The predicted gaze vector should be [0,0,1] when you look into the camera. It should not matter where the camera is.
@erkil1452 then what should I do to make the gaze vector to be [0,0,1] when look into the camera, could you describle the procedure detail? I found some describles in your paper
for the formula
I want to confirm something :
1.the gL is the gaze vector predicted by our model ? and is the norm of gL?
You misunderstood. The output of the neural network should already be [0,0,1] (or -1?). You do not need to do anything.
@erkil1452 as you said, why I can't get the correct gaze vector when I predict the gaze vector with a video? but I can get the correct result when I use the camera within the labtop, as I sit in front of the labtop,and the eyes have the same height with the camera? I can't understand and I don't know why?
So it works for you with images from a webcam? That is great! Then you just need to debug what is wrong with the video sequence. I am sure it must be some small error somewhere. Perhaps try to record video from your webcam to make the conditions as similar as possible.
ok, I will try it tomorrow, maybe there are still some question want to consult you
@erkil1452 I find the problem and solved it, thankyou
Glad to hear that!
@erkil1452 hello, I'm sorry to trouble you again. I test my own trained model using the camera that comes with the laptop, the camera is on the top-midde of the labtop. when I sit in the front of my labtop , the position of the eyes are on the same height of the camera, I got the correct gaze vector. However, when I test my own trained model using the video from the website, the gaze vector is not correct, I don't know why? whether I should do some thing like normalization of the head? another similar question is : when the tester is not in front of the camera, maybe there are some angles between the camera and the eyes(for example, the camera is on the left side or right side of the tester, or the camera looks up at the face), how can I get the correct gaze vector? thankyou!
