What has been done

With this PR, we are now setting left and right eye with respect to the person instead of observer. This approach is adopted in biology as well.

How to test

make lint && make test

Proof of concept

from deepface import DeepFace
import matplotlib.pyplot as plt
import cv2

img_path = "/Users/sefik/Desktop/target.jpg"
img = cv2.imread(img_path)

    "opencv",

    "dlib",
    "mtcnn",
    "fastmtcnn",
    "retinaface",
    # "mediapipe"
    "yunet",
    "yolov8"
]

for detector_backend in detector_backends:
    face_objs = DeepFace.extract_faces(
        img_path=img_path,
        detector_backend=detector_backend,
        target_size=None,
        # expand_percentage=0,
    )
    fig = plt.figure(figsize=(10, 10))
    for face_obj in face_objs:
        face = face_obj["face"]

        print(detector_backend)
        facial_area = face_obj["facial_area"]
        x = facial_area["x"]
        y = facial_area["y"]
        w = facial_area["w"]
        h = facial_area["h"]
        le = facial_area["left_eye"]
        re = facial_area["right_eye"]
        current_img = img.copy()
        current_img = cv2.rectangle(current_img, (x, y), (x + w, y + h), (67, 67, 67), 1)
        current_img = cv2.circle(current_img, (le), radius=5, color=(0, 0, 255), thickness=-1) # red
        current_img = cv2.circle(current_img, (re), radius=5, color=(255, 0, 0), thickness=-1) # blue

        plt.imshow(current_img[:,:,::-1])
        plt.axis("off")
        plt.show()
       
        print("-----------")
