Hi there
Is there any code/library to draw these four lines (or measure their lengths) on a face with OpenCV, and without dlib? The angle of the jaw if available will be great as well.
Thank you.

there are 68 point Facemark classes in the contrib repo, similar to what dlib does
import random
import numpy as np
import cv2 as cv
frame1 = cv.imread(cv.samples.findFile('lena.jpg'))
if frame1 is None:
print("image not found")
exit()
frame = np.vstack((frame1,frame1))
facemark = cv.face.createFacemarkLBF()
try:
facemark.loadModel(cv.samples.findFile('lbfmodel.yaml'))
except cv.error:
print("Model not found\nlbfmodel.yaml can be download at")
print("https://raw.githubusercontent.com/kurnianggoro/GSOC2017/master/data/lbfmodel.yaml")
cascade = cv.CascadeClassifier(cv.samples.findFile('lbpcascade_frontalface_improved.xml'))
if cascade.empty() :
print("cascade not found")
exit()
faces = cascade.detectMultiScale(frame, 1.05, 3, cv.CASCADE_SCALE_IMAGE, (30, 30))
show original
