有没有一种方法可以使用OpenCV函数来执行基于眼睛检测的人脸识别？

import cv2
import numpy as np

face_cascade = cv2.CascadeClassifier('path/to/haarcascade_frontalface_default.xml')
eye_cascade = cv2.CascadeClassifier('path/to/haarcascade_eye.xml')

img = cv2.imread('path/to/image.jpg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

faces = face_cascade.detectMultiScale(gray, scaleFactor=1.3, minNeighbors=5)

for (x, y, w, h) in faces:
    roi_gray = gray[y:y+h, x:x+w]
    roi_color = img[y:y+h, x:x+w]
    eyes = eye_cascade.detectMultiScale(roi_gray)
    for (ex, ey, ew, eh) in eyes:
        cv2.rectangle(roi_color, (ex, ey), (ex+ew, ey+eh), (0, 255, 0), 2)

cv2.imshow('Face Detection', img)
cv2.waitKey(0)
cv2.destroyAllWindows()
