Tracking js face recognition

Face detection, recognition and tracking are revolutionary technologies that have been deployed on mobile phones, webcams, and digital cameras. With the help of this advancement in technology, we are now able to detect human faces and recognize any specific person in a crowd.

This is a really superb and game changer innovation that has taken the technology world by storm. In digital cameras, face detection technology is used for the purpose of autofocus; in webcams, it is used to take an instant passport-sized photograph of you; and in mobile phones, it is one measure used for the authentication of its user.

The future of face detection and recognition technology is very promising. This is because it is successfully used by the police and other law enforcement agencies to detect and fight crime in many countries of the world. Different machine learning algorithms are in place to achieve the purpose of detecting and recognizing a face. This is not a simple or straightforward task but some highly professional programmers have created different JavaScript libraries and frameworks to help us use this new technology in our web applications.

This JavaScript library is packed with a deluge of algorithms and capabilities for tackling different aspects of face detection and recognition within a web browser. It works very instinctively. Face detection, recognition and color tracking are done instantly. This is one of the best JavaScript face detection and recognition libraries.

Live Demo Download. This is another JavaScript library for the detection and recognition of human faces. It makes use of the tensorflow. You can use this library to track and detect a face in real-time. You can download it from GitHub for free. It makes use of Constrained Local Models to precisely identify and track the facial features.

It then returns an array, which contains all the coordinates of a face model. The interesting thing about clmtrackr is that it is capable of face swapping and masking. It really forms an all-in-one package. One of the JavaScript face detection and recognition libraries is pico. It is made up of roughly lines of clean JavaScript code.

In its GitHub repository, you will find 3 major folders e. All of these folders contain basic demo of how this library works. It runs perfectly on typical webcams. The face detection is very effective because it can easily work in all kinds of lighting conditions. Its features include face detection and tracking, mouth opening detection, face rotation detection, detect multiple faces, support for 3D engines like BABYLON. It is highly mobile-friendly too.

This is an object detection JavaScript library that runs smoothly on any web browsers. It gives its output in real-time. It is well supported by all the latest web browsing applications. Basically the main purpose of using this library is to bring computer vision right inside your favorite web browser without any issues. This is another face recognition program. It is available in the form of node. Apart from face recognition and detection, it also identifies face landmarks.

It makes use of an advanced algorithm to get an array of all the objects found in a face. These objects include coordinates, height and width, offset, position, scale and confidence of a face.

This is a face tracking JavaScript library demo. This JavaScript package is specifically developed for tracking the face and head of a person.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. So we have removed our main demo webojis. Thank you for your understanding. Build your own animated emoticon embedded in web applications with this library. The video is processed client-side only.

No devices are needed except a standard webcam. By default a webcam feedback image is overlaid by the face detection frame. The face detection will adapt to all lighting conditions, but the evaluation of expressions can be noisy if the lighting is too high, too weak, or if there is backlighting. The webcam feedback image is useful to see the quality of the input video feed. The computing power of your GPU is important. If your GPU is powerful, many detections per second will be processed and the result will be smooth and accurate.

An old or low quality mobile device it may be slower. But it should work well on medium or high end mobile devices. We have built a demo application based on this library, available on webojis. You can try them:. Piano Genie : play the piano with your face expressions!

This is pretty addictive. You can control the mouse cursor with your head turn your head to move the cursor, smile to click. Vautaby Nono : You can anime a. VRM 3D character avatar in the browser. This web application is only in Japanese.In this Instructable we will go over facial recognition.

Facial Recognition is integral to augmented reality and I have wanted to do something with it for a while. Recently Facebook implemented facial recognition and snapchat style filters so I though it would be fun to give it a go. Here I will go over tracking eyes and mouths with Tracking. We will attempt to make a snapchat style filter and also go over making some buttons and changing the overlay image on button presses.

If you have never heard of this library before it is definitely worth checking out because they have some other really cool samples like tracking colors or even moving a 3D seen by turning your head. The folder contains some images we will use in this Instructable and you can also try out the tracking at the link above before we continue. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.

First of all this will really only work in the web browser. It is only supported by Firefox and Google Chrome as far as I know. GetUserMedia also requires a secure connection so you have to use the https protocol in your web address. In order to follow along you will need to set up a basic web development environment with a text editor.

I use Sublime Text 2. You will also need some way to send files to your server. Since Tracking. If you don't want to link to a page but rather redirect all traffic to a secured version you can add a file in your main directory called ".

Go to www. If you have not already, go to www. Unzip both folders and put them into the working directory of your site. Upload both of them to your server. Go back to trackingjs. On the bottom right of the page click view source and copy that code to a new page of your site. Fix the references at the top to point to the correct files on your server, and add references for the eyes and mouth files like this:.

Finally, in the event. Upload that to your server and when you visit the page you will be prompted to allow camera access. When you click OK, you will see the image of the X being drawn over your mouth and eyes! Now you will see that more than 3 x's can get drawn at a time. As far as I know it is not possible to distinguish between what is currently being tracking in the event.

Word of warning I did try this, and it did not work very well. Now it is possible to create buttons and change the image on your face by clicking different buttons. I have compiled some code here for 4 buttons and each one will put a different version of nick cage over top of your face.

You can however change this stuff to display whatever images you would like. Here is everything you should need:. Honestly i tried, but it doesn't load any PNG image. I don't know where i'm doing wrong, seems everything ok.

ObjectTracker 'eye' ; tracker. Thanks anyway. Introduction: Facial Recognition With Tracking. By matthewh8 Check me out on YouTube!Java Script has been in existence for about twenty-five 25 years as it was created on the 4 th of December by Brendan Eich and others.

Face detection is using the Face detection jQuery algorithm. A JavaScript library is a library of preexisting JavaScript codes and commands that enables programmers swiftly and easily develop JavaScript-based applications. Remember that JavaScript is a programming language at such a JavaScript library that contains different codes that were written in JavaScript that programmers can refer to when trying to create an application or for other reasons.

Face detection is a new feature that was introduced in the 21 st century due to the improvement in science and technology and the need for more security and alertness in stores, offices, houses and so many others.

A typical example of tracking is when we are trying to track a stolen item especially a phone or a laptop and this act is possible because of JavaScript and the JavaScript libraries.

It is pertinent to note that we have a lot of amazing face detection JavaScript libraries because JavaScript is mostly used for face detection in the 21 st century.

We have compiled a list of some amazing and mind-blowing face detection JavaScript libraries below. The tracking. Another unique feature is that this face detection JavaScript creates a single platform or browser environment where different computer visions and algorithms are brought together.

7 Best Face Detection JavaScript Libraries

Hacking Stephen from Linda Rabs is the brain behind this wonderful face detection JavaScript library. This library comes with a full package detection and gender classification and not just face detection. Most people actually prefer the face recognition API and some refer to it as the best JavaScript library.

This face detection JavaScript library bears the general name face detection and it was created by Jay Salvat. Just like the tracking. It can detect faces from videos and images by using the algorithm by Lui Lui. It is not a basic face detection library as it does not only cover face detection but also properly analyzes different faces, height and width. The face detection. This face detection library is not compatible with all browsers, it is compatible with certain browsers such as the opera mobile and safari but it is not compatible with iso and explorer.

Paul Viola and Rainer Lienheart are the brains behind this particular face detection JavaScript library.One of the de-facto industry standards when it comes to computer vision is OpenCV. Open Source Computer Vision Library. It has been designed to focus on real-time application and is widely used for sophisticated use cases for example facial recognition.

In the browser. The days of server-side processing are gone. Enter tracking. So, are the days of OpenCV really over?

I do not think so. Although perfectly capable of face detectionfor exampletracking. Given its rapid pace of development and just how convenient it is to be able to work within the browser, tracking. What follows is a short series of experiments I made to get acquainted with the pros and cons of these two different approaches.

OpenCV includes functionality far beyond face recognition alone. It is a very complex library to be mastered, even considering how helpful opencv4nodejs is at abstracting away some of this complexity. On the other hand, OpenCV has shown itself to be immensely powerful and performant. The CascadeClassifier class can be used for object detection.

Vincent published a wonderful post about face recognition with opencv4nodejs:. My own experiment is largely based on such article and I have found the results to be definitely impressive. Time to test face detection using tracking. At line 80 I created an ObjectTracker that takes an array of classifiers as a parameter just 'face' in our example.

A classifier is an object that informs the behaviour of a tracker and teaches the latter how to recognise objects. Classifiers are to tracking.

I made some other experiments with different images, but the results were still unexpected:. I tracked the performances of both libraries.

I was already expecting the front-end tracking. Here is a first chart that compares the performance of the two libraries without considering any other variable:. So clearly opencv4nodejs is still more performant than tracking. Using tracking.

Out of the ordinary, I think the days of openCV are not finished at all. On the other hand a lot of machine learning tools and libraries are coming out everyday to perform this kind tasks as the technology itself improve, some are written in pure javascript, and some will probably be used instead of OpenCV in a near future.

For those who want to deepen about the code and the experiments, I packed the whole thing in a package on Github, feel free to use it, pull it and whatever you want. Sign in. About Beautiful Interactions Website. Antonio Russo Follow. Front-end or Back-end?I thought it would be funny if I could do the same, but with goofy pair of glasses. This library shows a few examples on static images, but after a quick look at the code, it shows that the underlying element to the script is a canvas element.

So instead of running it on a single image, I am running it on a feed of frames coming from an HTML5 video element. Currently tested and working in Google Chrome 14 and Firefox 6. Try the Demo Download the Source. To get started, we dont really need that much. We will also need an empty canvas element, a HTML5 video element with. MP4 and. Things will look like this when we are setup:. The core of this application is just a single function called html5glasses that runs every miliseconds.

The function grabs the current frame from the window, spits it onto the canvas and then lets the CCV JS library detect the face. When it returns the data we loop through each of the found faces and and apply the silly glasses. In the CCV examples, they provide a web worker example so we could do this asynchronously, but in my tests it was significantly slower. This is new technology and will only get better.

On my computer I see a new frame about every miliseconds, or 3 times a second. This is where all the magic happens. Read through each line and realize what is happening.

Pay specific attenton to the ccv. I'm just getting into CCV, but the library can be extended to recognize much more than just faces. If you take at look at the github repo, they have examples for detecting all kinds of things.

Next time I'm in the mood for a little hack, I'll try and hook this up to a flash webcam app or Mozilla's Rainbow to stream the data right from the device itself, giving us realtime funny glasses! Let me know if you have any ideas or questions. I'm wesbos on twitter and have hosted the source on Git Hub. Great post and a very neat example. Nice work! Wow the possibilities with this script are endless can do a lot with this! Thanks for the tutorial!

Really good explaination and idea. I was going to use flash for a similar effect for my 3rd year uni project. Really confused which way to go now!!!

Thanks for sharing. Finally Opera have released a desktop build that allows the browser access the webcam.
