Basic Usage

Prerequisites read

pip install opendbm

In this section, we are gonna show the basic instruction on how to get biomarker variable from OpenDBM API

from opendbm import Movement

# code below is how to access to other dbm groups
# from opendbm import FacialActivity, VerbalAcoustics, Speech
path = "movement_video_test.mp4"
#initiate the model
model = Movement()
#Feed input data to the model
model.fit(path)

After we processed the data with our model, now we can get all biomarker variables related to the Movement category

#Get facial tremor
tremor = model.get_facial_tremor()
tremor.to_dataframe().T
