Now, I could very well be wrong, but it looks like there’s a missing yawn in the following video session/JSON:
dmd/gA/3/s5/gA_3_s5_2019-03-13T09;36;25+01;00_rgb_face.mp4
dmd/gA/3/s5/gA_3_s5_2019-03-13T09;36;25+01;00_rgb_ann_drowsiness.json
It lists 4 yawn events:
action_id,action_type,start_frame,end_frame,start_time,end_time
5,yawning/Yawning with hand,2344,2470,78.763,82.997
5,yawning/Yawning with hand,4473,4634,150.302,155.712
6,yawning/Yawning without hand,3457,3624,116.163,121.774
6,yawning/Yawning without hand,3689,3731,123.958,125.37
Upon actually reviewing the footage, there’s a clear yawn that occurs at around 41–42 seconds.
Not sure if I’m interpreting the JSON wrong or if it’s an issue on my end?
