Feature Extraction Output #949

Open jonchuasoonkiat opened 3 years ago

jonchuasoonkiat commented 3 years ago

May I ask if the feature extraction from the windws GUI OpenFaceOffline.exe produced AU outputs (AU_r & AU_c) that are normalized?

I understand that under the API calls that there is a paragraph that writes "To extract AUs in a video look at FeatureExtraction.cpp for a detailed example that performs offline AU normalization, making it more accurate. This requires writing the AU predictions to file or memory so that they could later be corrected." However, i'm unsure if this automatically works for the offline program of OpenFace and if the output is already normalized.

If not, may i know if there is a way to do that for the output?

I do hope that someone can help me with this.

Thank you!

Hi,

OpenFaceOffline should perform such normalization as well.

Do you have reason to believe that it does not?
