使用face_recognition进行人脸识别
使用face_recognition库可以快速实现人脸识别,具体步骤如下:
1.安装face_recognition库,可以使用pip命令进行安装:
```shell
pip install face_recognition
```
2.导入face_recognition库和需要用到的其他库:
```python
import face_recognition
import cv2
import numpy as np
```
3.加载已知人脸的图像并进行编码:
```python
known_image = face_recognition.load_image_file("known.jpg")
known_encoding = face_recognition.face_encodings(known_image)[0]
```
4.加载待识别的图像并进行编码:
```python
unknown_image = face_recognition.load_image_file("unknown.jpg")
unknown_encoding = face_recognition.face_encodings(unknown_image)[0]
```
5.比较已知人脸的编码和待识别人脸的编码,判断是否为同一个人:
```python
results = face_recognition.compare_faces([known_encoding], unknown_encoding)
if results[0] == True:
print("This is the known person!")
else:
print("This is not the known person!")
```
需要注意的是,使用face_recognition库进行人脸识别需要保证已知人脸的图像中只有一个人脸,否则需要对已知人脸的编码进行处理。
