densepose parts definition

Densepose data annotation has 24 parts of human body, but their part segmentation masks correspond to 14 parts of the body. You can find some definitions of 24 parts by refering the correspondence listed at the end of this page, https://github.com/facebookresearch/DensePose/blob/master/challenge/2019_COCO_DensePose/data_format.md

However, since there are no exact definitions for each part, I figured out the exact definition per each part by own visualization efforts.

Given correspondence at the page:

1, 2 = Torso, 3 = Right Hand, 4 = Left Hand, 5 = Left Foot, 6 = Right Foot, 7, 9 = Upper Leg Right, 8, 10 = Upper Leg Left, 11, 13 = Lower Leg Right, 12, 14 = Lower Leg Left, 15, 17 = Upper Arm Left, 16, 18 = Upper Arm Right, 19, 21 = Lower Arm Left, 20, 22 = Lower Arm Right, 23, 24 = Head

Detail definitions I found:

1 = torso back, 2 = torso front, 3 = right hand, 4 = left hand, 5 = left foot, 6 = right foot, 7 = upper leg right back, 8 = upper leg left back, 9 = upper leg right front, 10 = upper leg left front, 11 = lower leg right back, 12 =lower leg left back, 13 = lower leg right front , 14 = lower leg left front, 15 = upper arm left inside, 16 = upper arm right inside, 17 = upper arm left outside, 18 = upper arm right outside, 19 = lower arm left inside, 20 = lower arm right inside, 21 = lower arm left outside, 22 = lower arm right outside, 23 = right head, 24 = left head

If you are confused with the "inside" and "outside" labels for arms, think of how you fold you arms. The side towards which you fold your arm is the "inside".
