In davidecannatanuig/openFaceR: A pacakge for the convenient analysis of OpenFace data

test datasets

Description

Openfacer provides 4 test OpenFace datasets: John, Teddy, Lara and Paula. Together, they are collected in the "faces" object "test_faces".

Usage

john

paula

lara

teddy

test_faces

Format

Each of the four example face datasets in test_faces is composed by 538 variables. Lara has 2203 rows, teddy 3281, paula and john 5367. Each row in each of the examples contains information relative to one single frame, There are 30 frames per second.

frame

the order of the frame analysed

face_id

The identifier number of the face, as there is one face per video it is always 0

timestamp

the time of the frame in the video, in seconds

confidence

The confidence of OpenFace of providing high quality results - from 0 to 1

success

1 if the confidence is high enough for results being reliable, 0 if it is not

gaze_0_x to gaze_0_z

The coordinates of the gaze of the left eye

gaze_1_x to gaze_1_z

The coordinates of the gaze of the right eye

gaze_angle_x to gaze_angle_y

eye gaze direction in radians

eye_lmk_x_0 to eye_lmk_y_55

two dimensional coordinates of the eyes in pixels

eye_lmk_X_0 to eye_lmk_Z_55

three dimensional coordinates of the eyes in millimeters

pose_Tx to pose_Tz

The location of the head in respect of the camera in millimeters

pose_Rx, pose_Ry, pose_Rz

pitch, yaw and roll of the head in radiants

X_0Z_67

coordinates of the 67 3D face landmarks in millimeters

AU01_r to AU45_r

action units intensity, as a number from 0 - inactive - to 1 - completely active -

AU01_r to AU45_r

action units presence. 1 is present, 0 is not present
