mac安装face_recognition python3

1. 安装hrew

# 运行以下命令安装Homebrew，Homebrew默认被安装到/usr/local/Homebrew
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

# 添加环境变量，我装了oh-my-zsh，故将export命令添加到~/.zshrc中
echo 'export PATH=/usr/local/opt/opencv/bin:$PATH' >> ~/.zshrc

2. 安装cmake

brew install cmake
brew install boost
brew install boost-python --with-python3

如果是windows的话，需要到cmake官网下载

3. 安装X11窗口环境，点击下载
4. 安装dlib

pip install dlib

5. 安装face_recognition

pip install face_recognition

6. 使用示例

# 检测人脸
import face_recognition
import cv2

# 读取图片并识别人脸
img = face_recognition.load_image_file("data/test.jpg")
face_locations = face_recognition.face_locations(img)
print(face_locations)

# 调用opencv函数显示图片
img = cv2.imread("data/test.jpg")
cv2.imshow("base", img)

# 遍历每个人脸，并标注
for (top,right,bottom,left) in face_locations:
    start = (left, top)
    end = (right, bottom)

    color = (55,255,155)
    thickness = 3
    cv2.rectangle(img, start, end, color, thickness)

# 显示识别结果
cv2.imshow("new", img)

cv2.waitKey(0)
cv2.destroyAllWindows()
