TrackHandModule

from MediaPipeTools import TrackHandModule
# Here we are using the live webcam
cap = cv2.VideoCapture(0)
#This is the track hand module class
hand = TrackHandModule.HandTrack(max_num_hands=1,static_image_mode = False)

while True:
    _, frame = cap.read()
    frame = cv2.flip(frame, 1)
    #This command draws the landmarks on the hand if any visible in the frame
    hand.find_hand(frame)
    # This returns a list having the coordiantes of each landmark
    lmlist = hand.findPosition(frame)
    if len(lmlist) != 0:
        x1, y1 = int(lmlist[8][1]), int(lmlist[8][2])
        x2, y2 = int(lmlist[4][1]), int(lmlist[4][2])

        cv2.circle(frame, (int(lmlist[8][1]), int(lmlist[8][2])), 10, (255, 0, 0), cv2.FILLED)
        cv2.circle(frame, (int(lmlist[4][1]), int(lmlist[4][2])), 10, (255, 0, 0), cv2.FILLED)

    cv2.imshow("Controller", frame)
    if cv2.waitKey(1) & 0xFF == ord('d'):
        break
cap.release()
cv2.destoryAllWindows()

Same Coordinates tracking can be done by each of the modules For more info, see my github page

Landmarks

Each module detects or track something. But how to find these coordinates.Mediapipe finds the hand and plots the landmarks and gives them an id ###Hand

Pose

You see each has an id so we use the id to find that particular landmark
