Features of FaceIO

FaceIO provides several features that make it a robust face recognition system. Some of these features include:

• Facial Recognition

Facial recognition is the primary feature of FaceIO. It can detect and recognize facial images and videos. The facial recognition feature is built on deep learning algorithms, making it highly accurate.

• Face Detection

Biometric identification technology is a critical component of facial recognition. FaceIO can detect facial images and videos with high accuracy. The face detection feature is optimized to work even in low-light environments, making it useful in various settings.

• Face Verification

Face verification is the process of verifying whether a person's face matches their identity. FaceIO can verify a person's identity by comparing their face with a registered image or video. This feature is useful in security applications.

• Face Search

Face search allows users to search for faces in a large database of images or videos. FaceIO can search for faces in large datasets quickly and accurately, making it useful in law enforcement and security applications.

• Face Recognition Training

Face recognition training is the process of training the system to recognize specific faces. FaceIO provides tools for training the system to recognize faces, making it useful in various settings.

Prerequisites

Before we begin, make sure that you have created an account on the FaceIO website and obtained an API key. You will also need to have a basic understanding of HTML, CSS, and JavaScript.

Step 1: Import the FaceIO Library

The first step is to import the FaceIO library into your website or web application. You can do this by adding the following script tag to the head section of your HTML file:

<script src="https://cdn.faceio.net/fio.js">
</script>

This will load the FaceIO library onto your webpage.

Step 2: Enroll a User

The next step is to enroll a user in your facial recognition software. To do this, you need to capture a photo of the user's face and pass it to the FaceIO API. You can use the getUserMedia() function to capture the photo from the user's webcam:

navigator.mediaDevices.getUserMedia({ video: true }).then(function (stream) 
{
  var video = document.getElementById("video");
  video.srcObject = stream;
  video.play();
});

In the above code snippet, we are accessing the user's webcam using the getUserMedia() function and playing the video stream in a video element with the id "video."

Once you have captured the user's photo, you can pass it to the FaceIO API to enroll the user:

var image = document.getElementById("photo");
var canvas = document.createElement("canvas");
canvas.width = video.videoWidth;
canvas.height = video.videoHeight;
var context = canvas.getContext("2d");
context.drawImage(video, 0, 0, canvas.width, canvas.height);
image.src = canvas.toDataURL();
var fio = new FACEIO("<your_api_key>");
fio.enroll({ photo: image.src, userId: "user123" }).then(function (response) {
  console.log(response);
});

In the above code snippet, we have created a canvas element and have drawn the video stream onto it. We then convert the canvas to a data URL and pass it to the FaceIO API along with a user ID. The FaceIO API will extract facial features from the photo and enroll the user into the facial recognition systems.

Step 3: User Authentication

Now that you have enrolled a user, you can authenticate the user using face recognition algorithms. To do this, you need to capture a photo of the user's face and pass it to the FaceIO API for user authentication:

var image = document.getElementById("photo");
var canvas = document.createElement("canvas");
canvas.width = video.videoWidth;
canvas.height = video.videoHeight;
var context = canvas.getContext("2d");
context.drawImage(video, 0, 0, canvas.width, canvas.height);
image.src = canvas.toDataURL();
var fio = new FACEIO("<your_api_key>");
fio.authenticate({ photo: image.src }).then(function (response) {
  console.log(response);
});

In the above code snippet, we create a canvas element and draw the video stream onto it. We then convert the canvas to a data URL and pass it to the FaceIO API for user authentication. The FaceIO API will start measuring the facial features of the enrolled user to compare the photo and return a response indicating whether the user is authenticated.

Step 4: Displaying Authentication Results

Once the authentication response is returned, you can display the user authentication results to the user. For example, you can display a message indicating whether the user was successfully authenticated or not:

var result = document.getElementById("result");
if (response.success) {
  result.innerText = "User Authentication successful!";
} else {
  result.innerText = "User Authentication failed.";
}

In the above code snippet, we are displaying a message to the user indicating whether the user authentication factor was successful or not.

Step 5: Managing Facial Index and Metrics Reports

Once you have enrolled and authenticated users using FaceIO, you can manage your application's facial index and collect real-time metrics reports. You can do this by logging into the FaceIO console and navigating to the “Facial Index” and “Metrics” sections.

In the “Facial Index” section, you can view and manage your application's facial index. This includes the list of enrolled users and their associated facial features.

In the “Metrics” section, you can view real-time metrics reports on your facial recognition system usage. This includes metrics such as the number of enrollments, authentication factor, and errors.
