通過Python的face_recognition模組實現人臉檢測功能，首先需要安裝好face_recognition包：可通過pycharm直接安裝，也可以用pip安裝，還可以通過anaconda安裝。

示例程式碼如下：

# -*- coding: utf-8 -*-
# 自動識別人臉特徵
# filename : find_facial_features_in_picture.py

from PIL import Image, ImageDraw
import face_recognition

# 將jpg檔案載入到numpy 陣列中
image = face_recognition.load_image_file("linuxidc.com.jpg")

#查詢影象中所有面部的所有面部特徵
face_landmarks_list = face_recognition.face_landmarks(image)

print("I found {} face(s) in this photograph.".format(len(face_landmarks_list)))
pil_image = Image.fromarray(image)
d = ImageDraw.Draw(pil_image)
for face_landmarks in face_landmarks_list:
#列印此影象中每個面部特徵的位置
facial_features = [
'chin',
'left_eyebrow',
'right_eyebrow',
'nose_bridge',
'nose_tip',
'left_eye',
'right_eye',
'top_lip',
'bottom_lip'
]
for facial_feature in facial_features:
print("The {} in this face has the following points: {}".format(facial_feature, face_landmarks[facial_feature]))
#在影象中畫出每個人臉特徵！
for facial_feature in facial_features:
d.line(face_landmarks[facial_feature], width=5)

pil_image.show()

自動識別出人臉特徵(輪廓)，如下圖：
