Linux实现的人脸识别与检测（linux人脸检测）

Nowadays, face recognition and detection is an indispensable part of life, withlinux face recognition technology being used to facilitate security and access control in banks and airports. In this article, we will discuss how to use Linux to implement face recognition and detection.

First, we will need to install the necessary packages on a Linux system. Packages such as opencv, face_recognition, imutils, and numpy are needed to perform Linux face recognition and detection. Installing the packages is simple, and the commands can be found in the opencv documentation.

Once the packages are installed, the next step is to create a motion detection script in Linux. Python and bash are both great scripting languages to use for Linux face recognition and detection. Python is particularly well-suited to this task, as it is easy to use and provides powerful tools for image manipulation and analysis. Here is a basic example of a motion detection script written in python:

import cv2, imutils, face_recognition

cam = cv2.VideoCapture(0)

while True:

ret, frame = cam.read()

# Resize and find the face in the frame

frame = imutils.resize(frame, width=500)

face_locations = face_recognition.face_locations(frame)

# Iterate over each located face

for (top, right, bottom, left) in face_locations:

# Draw a blue rectangle around the face

cv2.rectangle(frame, (left, top), (right, bottom), (0, 255, 0), 2)

# Show the frame

cv2.imshow(‘Detection’, frame)

# Quit program if ‘q’ is pressed

if cv2.waitKey(1) & 0xFF == ord(‘q’):

break

cam.release()

cv2.destroyAllWindows()

The next step is to create a recognition script. This script will be used to identify the faces in the frame and output the results. The recognition script will use the face recognition package to compare the face in the frame to the known faces in a database. This is the basic structure of the recognition script:

# Load known faces from the database

known_faces = face_recognition.load_image_file(‘known_faces.jpg’)

encode_known_faces = face_recognition.face_encodings(known_faces)[0]

# Iterate over each face in the frame

for face in face_locations:

# Encode the face

face_encoding = face_recognition.face_encodings(face)[0]

# Compare it to the known faces

match = face_recognition.compare_faces([encode_known_faces], face_encoding)[0]

# Output the results

if match:

print(‘MATCHED!’)

else:

print(‘NO MATCH!’)

With the motion detection and recognition scripts in place, we now have a fully functional Linux face recognition and detection system. This system can be used in many applications including security, access control, and identity verification. The scripts can be easily modified and added to in order to make the system more sophisticated and accurate. Linux face recognition and detection is an important technology in today’s society, and it is only getting better.
