手把手教你用1行代码实现人脸识别( 二 ) _人脸识别

# 将jpg文件加载到numpy 数组中
image = face_recognition.load_image_file("biden.jpg")
＃查找图像中所有面部的所有面部特征
face_landmarks_list = face_recognition.face_landmarks(image)
print("I found {} face(s) in this photograph.".format(len(face_landmarks_list)))
for face_landmarks in face_landmarks_list:
＃打印此图像中每个面部特征的位置
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]))
＃让我们在图像中描绘出每个人脸特征！
pil_image = Image.fromarray(image)
d = ImageDraw.Draw(pil_image)
for facial_feature in facial_features:
d.line(face_landmarks[facial_feature], width=5)
pil_image.show()
自动识别出人脸特征(轮廓)

示例四(识别人脸鉴定是哪个人)：
# filename : recognize_faces_in_pictures.py
# -*- conding: utf-8 -*-
# 导入face_recogntion模块，可用命令安装 pip install face_recognition
import face_recognition
＃将jpg文件加载到numpy数组中
babe_image = face_recognition.load_image_file("/opt/face/known_people/babe.jpeg")
Rong_zhu_er_image = face_recognition.load_image_file("/opt/face/known_people/Rong zhu er.jpg")
unknown_image = face_recognition.load_image_file("/opt/face/unknown_pic/babe2.jpg")
＃获取每个图像文件中每个面部的面部编码
＃由于每个图像中可能有多个面，所以返回一个编码列表。
＃但是由于我知道每个图像只有一个脸，我只关心每个图像中的第一个编码，所以我取索引0 。
babe_face_encoding = face_recognition.face_encodings(babe_image)[0]
Rong_zhu_er_face_encoding = face_recognition.face_encodings(Rong_zhu_er_image)[0]
unknown_face_encoding = face_recognition.face_encodings(unknown_image)[0]
known_faces = [
babe_face_encoding,
Rong_zhu_er_face_encoding
]
＃结果是True/false的数组，未知面孔known_faces阵列中的任何人相匹配的结果
results = face_recognition.compare_faces(known_faces, unknown_face_encoding)
print("这个未知面孔是 Babe 吗? {}".format(results[0]))
print("这个未知面孔是容祖儿吗? {}".format(results[1]))
print("这个未知面孔是我们从未见过的新面孔吗? {}".format(not True in results))
显示结果下如图

示例五(识别人脸特征并美颜)：
# filename : digital_makeup.py
# -*- coding: utf-8 -*-
# 导入pil模块，可用命令安装 apt-get install python-Imaging

# 导入face_recogntion模块，可用命令安装 pip install face_recognition

image = face_recognition.load_image_file("biden.jpg")
＃查找图像中所有面部的所有面部特征
face_landmarks_list = face_recognition.face_landmarks(image)
for face_landmarks in face_landmarks_list:
pil_image = Image.fromarray(image)
d = ImageDraw.Draw(pil_image, 'RGBA')
＃让眉毛变成了一场噩梦
d.polygon(face_landmarks['left_eyebrow'], fill=(68, 54, 39, 128))

＃涂一些眼线

d.line(face_landmarks['right_eye'] + [face_landmarks['right_eye'][0]], fill=(0, 0, 0, 110), width=6)
