some problem about the predict about gaze360

[liyixin-1]

@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?
2. then how to calculate the E when I predict the gaze using a video or a image capture with the camera within the labtop?

[erkil1452]

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

[erkil1452]

Glad to hear that!
