Face Recognition with Python [source code included]

Python can detect and recognize your face from an image or video

Face Detection and Recognition is one of the areas of computer vision where the research actively happens.

The applications of Face Recognition include Face Unlock, Security and Defense, etc. Doctors and healthcare officials use face recognition to access the medical records and history of patients and better diagnose diseases.

About Python Face Recognition

In this python project, we are going to build a machine learning model that recognizes the persons from an image. We use the face_recognition API and OpenCV in our project.

Tools and Libraries

• Python – 3.x
• cv2 – 4.5.2
• numpy – 1.20.3
• face_recognition – 1.3.0

To install the above packages, use the following command.

pip install numpy opencv-python

To install the face_recognition, install the dlib package first.

pip install dlib

Now, install face_recognition module using the below command

pip install face_recognition

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

#python #anonymous function python #filter function in python #lambda #lambda python 3 #map python #python filter #python filter lambda #python lambda #python lambda examples #python map

Face Recognition with Python and OpenCV

What is face recognition? Or what is recognition? When you look at an apple fruit, your mind immediately tells you that this is an apple fruit. This process, your mind telling you that this is an apple fruit is recognition in simple words. So what is face recognition then? I am sure you have guessed it right. When you look at your friend walking down the street or a picture of him, you recognize that he is your friend Paulo. Interestingly when you look at your friend or a picture of him you look at his face first before looking at anything else. Ever wondered why you do that? This is so that you can recognize him by looking at his face. Well, this is you doing face recognition.

But the real question is how does face recognition works? It is quite simple and intuitive. Take a real-life example, when you meet someone first time in your life you don’t recognize him, right? While he talks or shakes hands with you, you look at his face, eyes, nose, mouth, color, and overall look. This is your mind learning or training for the face recognition of that person by gathering face data. Then he tells you that his name is Paulo. At this point, your mind knows that the face data it just learned belongs to Paulo. Now your mind is trained and ready to do face recognition on Paulo’s face. Next time when you will see Paulo or his face in a picture you will immediately recognize him. This is how to face recognition work. The more you will meet Paulo, the more data your mind will collect about Paulo and especially his face, and the better you will become at recognizing him.

Now the next question is how to code face recognition with OpenCV, after all this is the only reason why you are reading this article, right? OK then. You might say that our mind can do these things easily but to actually code them into a computer is difficult? Don’t worry, it is not. Thanks to OpenCV, coding face recognition is as easier as it feels. The coding steps for face recognition are the same as we discussed in the real-life example above.

• Training Data Gathering: Gather face data (face images in this case) of the persons you want to recognize
• Training of Recognizer: Feed that face data (and respective names of each face) to the face recognizer so that it can learn.
• Recognition: Feed new faces of the persons and see if the face recognizer you just trained recognizes them.

OpenCV comes equipped with a built-in face recognizer, all you have to do is feed it the face data. It’s that simple and this how it will look once we are done coding it.

Fuse with the radical technology using the Face Recognition Employee Attendance Software

We are witnessing a lot of impacts in the world because of the COVID-19 pandemic. There is not much we could do to compensate for all the losses at once. But it can eventually be overcome. And the reason for this hope is ‘technology’.

Everything is just at an arm’s reach with the technology and it’s been proven time-to-time to us. One such thing that makes people still and stare for a moment is the Face Recognition Employee Attendance Software.

Face recognition is one of the most advanced technologies that is being implemented in the corporate industry now.

The software is mainly responsible for marking the attendance of the employees without them having to touch the screen.

Since ‘touch’ has become the most dangerous word in recent months, the system helps people to get away from it.

This software is also known as Contactless Attendance System that follows a highly hygiene scanning. Let’s look at the workflow:

• The employee would stand in front of the device camera and the facial features get analysed. *
• The features are then compared with the database containing the faces of all the employees. The user details are retrieved from the database.*
• The user will be scanned to ensure that he/she has a mask and once they put the mask on, the system scans the face again.*
• The social distancing guidelines are examined by scanning the area around the user. *
• Once the criterias are matched, the attendance of the user is marked.

Working models of the software:
The software works in two different models such as:

Tab-based model:
The tablet having this software solution, will have to scan their faces at the entry points. They will wait for the system to confirm the checklist like detecting face masks and social distancing.

Mobile-based model:
The mobile-based model is safer, since it involves logging in with the WiFi server and login to the accounts. After matching the criteria, attendance would be marked.

On a concluding note, Employee contactless attendance software is the future. So, make the most out of it by contacting our team right now!
