人生苦短，我用Python：26行Python代码实现AI人脸识别

通过Python的face_recognition模块实现人脸检测功能，首先需要安装好face_recognition包：可通过pycharm直接安装，也可以用pip安装，还可以通过anaconda安装。

示例代码如下：

# -*- coding: utf-8 -*-# 自动识别人脸特征# filename : find_facial_features_in_picture.pyfromPILimportImage, ImageDrawimportface_recognition# 将jpg文件加载到numpy 数组中image = face_recognition.load_image_file("linuxidc.com.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)))pil_image = Image.fromarray(image)d = ImageDraw.Draw(pil_image)forface_landmarksinface_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']forfacial_featureinfacial_features:        print("The {} in this face has the following points: {}".format(facial_feature, face_landmarks[facial_feature]))#在图像中画出每个人脸特征！forfacial_featureinfacial_features:        d.line(face_landmarks[facial_feature], width=5)pil_image.show()

自动识别出人脸特征(轮廓)，如下图：
