# 步骤1: 加载预训练的人脸检测模型
face_detector = dlib.get_frontal_face_detector()
# 步骤2: 读取图片
image_path = r"E:\person1.jpg"

# 步骤3: 检测图片中的人脸
dets = face_detector(image, 1)
# 步骤5: 在检测到的人脸周围画矩形框
for i, d in enumerate(dets):

cv2.rectangle(image, (x1, y1), (x1 + w, y1 + h), (0, 255, 0), 2)
# 步骤6: 显示图片
cv2.imshow("Detected Faces", image)
