How to read csv output by OpenFaceOffline ? #25

l-h-e · 2020-07-29T08:20:45Z

OpenFaceOffline can output csv as a result of face recognition .
I can manipulate avatar's face on Unity3D by reading csv with main.py .
However , csv output by OpenFaceOffline has too argument to use main.py .

Can I make main.py read csv output by OpenFaceOffline without format by change the code of main.py ?
Is it same that csv output by OpenFaceOffline and csv can read by main.py (for example , demo.csv has only three gaze parameter , three pose parameter and AU1_r ~ AU45_r , but csv output by OpenFaceOffline has more parameters .) ?

This seems to be related to this issue: #23
Please check that issue for updates.

Thank you for your reply .
How about question 2 ?

NumesSanguis · 2020-07-30T09:27:06Z

If I remember correctly, FACSvatar is not using the other parameters. Therefore, the non-relevant columns have been removed from demo.csv to reduce file size.
If issue 1 is solved, main.py would just ignore the extra columns outputted by OpenFaceOffline.

Thank you .
I checked they are same by outputting received message in Unity3D .
However , they are slightly difference .
OpenFaceOffline's message includes "PoseTx , Ty , Tz" and "AU01~46" , but csv message has not .
I think the result as move of avatar must be same with same movie , however avatar's moving is a bit difference . (particular mouth moving is difference)
Is it specification or my setting issue ?

About issue 1, I think you've put your OpenFace .csv in to FACSvatar\modules\input_facsfromcsv\openface\default_clean\your_recording.csv, right? .csv produces by OpenFace should not be put in a folder with a name ending in _clean. edited

I'm rewriting the documentation for FACSvatar v.0.4.0, and I hope these instructions will make it a bit clearer how to use your own files: https://facsvatar.readthedocs.io/en/v0.4.0/trackers/openface.html#use-your-own-videos

OpenFaceOffline's message includes "PoseTx , Ty , Tz"

That is correct, FACSvatar only uses "pose_Rx, Ry, Rz"

and "AU01~46" , but csv message has not .

Can you describe in more detail what you mean? FACSvatar uses the same AU values as OpenFace.

I think the result as move of avatar must be same with same movie , however avatar's moving is a bit difference . (particular mouth moving is difference)

OpenFace's facial expression tracking is not perfect, so some differences are to be expected.
It would be nice to use a better FACS tracker, however I'm not aware of an open FACS tracker that performs better than OpenFace.

I see.

This is the output in Unity3D with Debug.Log(facsvatar); if I use OpenFaceOffline.

There are a bit difference .

Thank you for the detailed log!

"au_c" means classification if that AU is active or not. Basically it means that if au_r >= 0.5 then it's 1, else 0. This value is not used in FACSvatar.
"pose_Tx" is also ignored.

There is some slight difference in using OpenFaceOffline for real-time purposes, or when using the .csv. In general, the .csv is more accurate and therefore preferred when real-time is not necessary. Apparently, OpenFace does some post-processing after analysing the whole file, when it writes the results to a .csv file. This does not happen when using it in real-time.

Thank you for reply .
I see .
and I have another question that how to use 2 model with csv input .
in default status , I can receive following message

Received message: ['openface.p0.somefile, 15965343864475856, {'confidence': 0.98, 'frame': 22, 'timestamp': 0.738, 'au_r': {'AU01': 0.09726842766153403, 'AU02': 0.034993200875877276, 'AU04': 3.0209638855816707, 'AU05': 0.006224593312018546, 'AU06': 0.0, 'AU07': 2.0982603297049134, 'AU09': 0.027994560700701818, 'AU10': 1.5865665697855156, 'AU12': 0.0, 'AU14': 0.0, 'AU15': 0.04173519116644401, 'AU17': 0.23696478524592737, 'AU20': 0.03250339956206137, 'AU23': 0.03250339956206137, 'AU25': 0.1875066408505329, 'AU26': 0.18623398961520926, 'AU45': 0.0, 'AU61': 0.268, 'AU62': 0, 'AU63': 0, 'AU64': 0.017}, 'pose': {'pose_Rx': -0.15426555630457997, 'pose_Ry': 0.4306318043153648, 'pose_Rz': -0.05582972387846044}, 'timestamp_utc': 15965343864141326}]

I want to change "p0" to "p1" .
What should I do ?

NumesSanguis · 2020-08-05T02:22:39Z

Do you want 2 models with the same facial expressions (1 .csv), or 2 models with different facial expressions (2 .csv)?

In case of 2 .csv, you need to follow this naming scheme:

some_name_p0.csv
some_name_p1.csv
https://github.com/NumesSanguis/FACSvatar/tree/master/modules/input_facsfromcsv/openface/default_clean

Let me give you later some more detailed instructions.

l-h-e · 2020-08-05T06:46:55Z

Thank you for reply .
I used following command .

python main.py --csv_arg 2people_60fps_p1.csv --pub_ip facsvatar_bridge .

and My UnityMainThreadDispatcher's Participants state is "Users_2_models_2".
However , The woman avatar only moves .
Docker received message "Received message: ['openface.p0.2people_60fps_p1' ... " .
What should I do ?

NumesSanguis · 2020-08-05T09:06:29Z

I'll get back to you, but I believe changing p1 to p* does the trick. So it would be:
python main.py --csv_arg 2people_60fps_p*.csv --pub_ip facsvatar_bridge

Then it sends the facial data of p0.csv to the 1st avatar, and p1.csv to the 2nd avatar.

l-h-e · 2020-08-06T06:36:42Z

Thank you for reply .
I see.
I tried this command and I can make 2 avatars move .

python main.py --csv_arg 2people_60fps_p*.csv --pub_ip facsvatar_bridge
