Plotting yaw and roll angles

[sarmadm]

HI

I have question , I want to draw yaw angles and roll , how can I do something like this image : head pose plot

You can find such an example in the gazr fork: severin-lemaignan@fc26ca2

I compiled gazr and attention tracker . for attentatio tracker it works fine with this command : ./head_pose_test ../share/shape_predictor_68_face_landmarks.dat .

but with gazr this error shows :
opengl support available
(ERROR)icvOpenAVI_XINE(): Unable to initialize video driver.
Couldn't open camera

when I tried to run live_plot.py :

./estimate_gaze_direction -c --model=shape_predictor_68_face_landmarks.dat | python -u live_plot.py

this error shows :

tofi@tofi:~/gazr/build$ ./estimate_gaze_direction -c --model=shape_predictor_68_face_landmarks.dat | python -u live_plot.py
bash: ./estimate_gaze_direction: No such file or directory
python: can't open file 'live_plot.py': [Errno 2] No such file or directory

@sarmadm These are basic mistakes, and I fear that github issues are not the right place to teach about the basics of computer science... that said:

• gazr is a fork of attention_tracker: they do the same thing. If you launch both, one will fail as only one process can access the webcam at a time. In your case, do not start attention_tracker. Only use gazr.
• python does not find live_plot.py because you are not in the right directory. $ ./estimate_gaze_direction -c --model=shape_predictor_68_face_landmarks.dat | python -u ../tools/live_plot.py should work.

When I run :

tofi@tofi:~/gazr-master/build$ ./estimate_gaze_direction -c --model=shape_predictor_68_face_landmarks.dat | python -u ../tools/live_plot.py
