A real time face recognition system is capable of identifying or verifying a person from a video frame. To recognize the face in a frame, first you need to detect whether the face is present in the frame. It automatically creates Train folder in Database folder containing the face to be recognised.

While creating the database, the face images must have different expressions, which is why a 0. Training and face recognition is done next. Face detection is the process of finding or locating one or more human faces in a frame or image. Haar-like feature algorithm by Viola and Jones is used for face detection.

In Haar features, all human faces share some common properties. These regularities may be matched using Haar features, as shown in Fig.

For example, the difference in brightness between white and black rectangles over a specific area is given by:. The above-mentioned four features matched by Haar algorithm are compared in the image of a face shown on the left of Fig. The project was tested on Ubuntu Create the database and run the recogniser script, as given below also shown in Fig.

Make at least two data sets in the database. This will start the training, and the camera will open up, as shown in Fig. Accuracy depends on the number of data sets as well as the quality and lighting conditions. LBP works on gray-scale images. For every pixel in a gray-scale image, a neighbourhood is selected around the current pixel and LBP value is calculated for the pixel using the neighbourhood.

After calculating LBP value of the current pixel, the corresponding pixel location is updated in the LBP mask it is of same height and width as input image. In the image, there are eight neighbouring pixels. If the current pixel value is greater than or equal to the neighbouring pixel value, the corresponding bit in the binary array is set to 1.

But if the current pixel value is less than the neighbouring pixel value, the corresponding bit in the binary array is set to 0. Interested in face detection projects?

The reply from author Aquib Javed Khan.Security is a major concern in our day to day life, and digital locks have become an important part of these security systems.

There are many types of security systems available to secure our place. Here all the process is commanded by Arduino like taking an image of finger print, convert it into templates and storing location etc. Every key has double features. Enroll key is used for enrolling new finger impression into the system and back function as well. Means enroll key has both enrollment and back function. Check the Video at the end for full demonstration. Here we have also attached a cardboard box with a Servo Motor to act as a security gate, which will only open when the system will read correct Finger Print.

Working of this Fingerprint Sensor Door Lock is easy. In this project, we have used a gate that will be open when we place stored finger at the finger print module. Now LCD will ask for placing finger over the finger print module.

You can learn Arduino in 15 minutes.

Now user needs to put his finger over finger print module. Then LCD will ask to remove the finger from finger print module and again ask for placing the finger. Now user needs to put his finger again over finger print module. By the same method, the user can add more fingers.

I want to make it very well. Hello sir,it is very helpfull. I have error when i Placed my finger error msg is " Finger not found try again later ". Dear Sir.Updated 07 Jun The steps of the experiment process are; 1. Initiate capturing the images through the camera which is able to rotate in all direction in the class room. Pre-process the captured images through and extract face image. Calculate the eigen value of the captured face image and compared with that of the existing face images.

If the eigen value does not matches with the existing one,save it as a new face image. If the eigen values matches, then the recognition process will start soon. Using PCA algorithm the following steps would be followed 7. Find the face information of matched face image in the database. Update the log table with corresponding face image and system time that makes completion of attendance for an individual students. This section presents the results of the experiments.

With advances in computing and telecommunications technologies, digital images and video are playing key roles in the present information era. Human face is an important biometric object in image and video databases of surveillance systems. Detecting and locating human faces and facial features in an image or image sequence are important tasks in dynamic environments, such as videos, where noise conditions, illuminations, locations of subjects and pose can vary significantly from frame to frame.

An automated system for human face recognition in real time background for a college to mark the attendance of their employees and students. So Smart Attendance using Real Time Face Recognition is a real world solution which comes with day to day activities of handling employees. Here multiple user faces are detected and recognised with the data base trained multiple texture based features. LBP is a simple yet very efficient texture operator which labels the pixels of an image by thresholding the neighborhood of each pixel and considers the result as a binary number.

Due to its discriminative power and computational simplicity, LBP texture operator has become a popular approach in various applications. It can be seen as a unifying approach to the traditionally divergent statistical and structural models of texture analysis.

Perhaps the most important property of the LBP operator in real-world applications is its robustness to monotonic gray-scale changes caused, for example, by illumination variations.

Another important property is its computational simplicity, which makes it possible to analyze images in challenging real-time settings. However, many of the previously mentioned properties can be attributed to nonneural models.

A hybrid approach combining AdaBoost and ANN is proposed to detect faces with the purpose of decreasing the performance time but still achieving the desired faces detecting rate.

The selected neural network here is three-layer feedforward neural network with back propagation algorithm. Thus the attendance are recorded in the database by the comparison with the image present in the image enrolment database by the use of neural networks.

Bring the power of face unlock to your shelf, door or wardrobe with Bolt IoT. Project tutorial by Divins Mathew. Welcome, curious pal! We live in an internet revolutionized era where it is now easier than ever to experiment and innovate ourselves to come up with brilliant ideas that can have a positive impact on millions around the world. Ever wanted to add a little bit of extra security to your shelf, drawers, wardrobes or doors at home?

When it comes to innovation using internet, among thousands of platforms and tools available to us, a couple that stand out are Arduino and Bolt IoT.

Attendance Record System (Arduino + RFID)

In this project, we'll modify a standard shelf to have a security system that unlocks using Face Verification. We'll build a Windows Forms Application in C that can store, verify and unlock trusted faces. A synopsis of Capstone Project done as a part of this training can be found here. A lot of these concepts came in handy during the course of development of this project.

So a big shout out to the Internshala Team for making this possible. We'll be using C to code. This and this are good resources to get started. In this tutorial, I'll only be explaining code using snippets from the project that does main and important functions. It'll be tedious and unnecessary to go through the entire code as most of it is self explanatory and well documented.

NOTE: For clarity in usages of different methods in the above APIs, please refer to their respective documentations herehere and here. If you haven't already, to to cloud. Follow the instructions given in the app to link your device with your account. This involves pairing the Bolt with local WiFi network. Once successfully linked, your dashboard will display your device.

It's a free platform that offers various kinds of image recognition services. We use it for facial identification. Create an account and go to the FacePlusPlus console. We create a new global instance of the Bolt class called myBoltthrough which we'll do all the future communications with the WiFi Module:.

This'll be made more clear later when we discuss the circuit schematics. This will signal the Arduino to lock the door. This will signal the Arduino to unlock the door. We'll discuss the Arduino code and circuit design later in this tutorial. The trusted face's image data is encoded into a Base64 string and is stored locally in the machine. A list of corresponding names of each face is also stored. In our program, to add a face, we first verify if there is a face available in the current frame.

It returns a JSON response that will contain features of the detected face. If no face is detected the response will simply be []. Once a face is detected, we save the image's base64 encoded string and corresponding name. Here's a video demo of adding a trusted face. Removing a face is pretty straight forward. Pressing the remove button will delete the image data and name from the saved list.Did you use this instructable in your classroom?

Add a Teacher Note to share how you incorporated it into your lesson. Everything you need from OpenCV to build this project has already been generated in this download. This is not a one-click job.

The OpenCV team tested version 2. If you are using a different configuration, be prepared for a few hiccups. I did not want to affix any of the project parts permanently because I like to take my projects apart after I am done. So I used hobby wire, which is nothing more than a stiff wire, to tie the servos and the webcam together. I wrapped the base of the webcam to the pan servo horn. Then I wrapped a cable around the horn of the tilt servo and the body of the pan servo.

It kept is steady during servo rotation. It ain't pretty but it works. The wiring is straight forward. I used a breadboard to make the connections. You will see a check mark next to the active USB port. Reply 6 years ago on Introduction. Reply 1 year ago. Question 2 years ago.

S R Dhanush. Chetan R Assistant Professor, Dept. The report has been approved as it satisfies the academic requirements in respect of Project Work prescribed for the said degree. Chetan R Dr. Thirumaleshwara Bhat Dr. Balachandra Achar Asst. Mainly there are two conventional methods of marking attendance which are calling out the roll call or by taking student sign on paper.

They both were more time consuming and difficult. Hence, there is a requirement of computer-based student attendance management system which will assist the faculty for maintaining attendance record automatically. The application includes face identification, which saves time and eliminates chances of proxy attendance because of the face authorization. Hence, this system can be implemented in a field where attendance plays an important role.

This algorithm compares the test image and training image and determines students who are present and absent. The attendance record is maintained in an excel sheet which is updated automatically in the system.
