A face isn't quite equally unique and ageless as a fingerprint, but it'due south easily captured and searched. Facial recognition, in combination with data from surveillance cameras or online profiles, is a powerful tool in finding people and tracking their every step. On the entertaining cease of the spectrum, a face up search can reveal your online (celebrity) lookalikes or your age.

Here are several face recognition search engines that may give you a thrill. Let's see what they reveal about yous or your friends.

Did y'all know that you could search Google by images? Rather than a keyword, you can use an epitome to search for similar images.

Click the photographic camera icon to search by paradigm. Yous tin either paste the image URL or upload an image and Google will find like images.

Moreover, you lot can make Google search for faces just by adding a pocket-size bit of lawmaking.

When y'all go to Google Images Search, enter your query, hit Enter, and then add "&imgtype=face" (without the quotes), either to the cease of the search URL or right before some other string starting with &. This will further improve the results of your face up-related search.

Beneath is a before and after example of a search for "basil" that you tin can try for yourself:

A Google image search for

Once yous add the image type to the URL, you'll also find this option under Tools > Type.

Google likewise offers its face recognition in Google Photos, meaning you can search your photos for people and fifty-fifty pets.

two. PicTriev: Face up Recognition

PicTriev goes one step further by actually searching for similar faces. Unfortunately, the feature is limited to lookalike celebrities.

What you do is add together the URL or upload a photo in JPG or JPEG format, with a size no larger than 200 KB, and the search engine volition return matching celebrity images found online.

For demonstration purposes, I used my ain headshot. While PicTriev correctly identified me as overwhelmingly female, the number one match was Jason Clarke. The age estimation of thirty, nevertheless, is very flattering.

It works much better if you search for a celebrity paradigm.

PicTriev also lets you compare the similarity of two faces or estimate whether photos of two faces are the same person. Click the meter icon on the top correct, upload two photos, select similarity or identity, and let PicTriev exercise its calculations.

Earlier you add photos, exist certain to follow the instructions on formatting for the best results.

TinEye reverse image search engine works for faces.

TinEye'southward opposite paradigm search works almost like Google. You can upload an image or paste a URL and search for information technology. TinEye does not support whatsoever more search operators, making information technology both simpler and bones.

In my test, TinEye plant three results, 1 of which Google had not included because the site died years ago. Also, it missed a newer result that its big brother had picked up. To me, this indicates that TinEye's search alphabetize is largely outdated.

Unlike Google, TinEye links directly to the pages where it found the images and it skips similar images.

Similar to Google'southward reverse face search, PimEyes uses images and face recognition to search for similar faces on over 10 1000000 websites. The demos using celebrity faces like Angelina Jolie or Zac Efron look promising.

For example, you tin search for Jennifer Aniston's face using iv different photos at in one case. PimEyes volition detect the original photos, as well as other shots of Aniston.

Curiously, while the app does detect the original pictures used for the search, the similarity is just scored at around seventy percent. Shouldn't information technology exist closer to 100 pct? Or does the algorithm take image resolution, size, brightness, and other digital alternations into account?

PimEyes facial matching

I tried the service myself, providing PimEyes with three unlike photos of me to analyze.

There are other photos of me to be found online, but PimEyes didn't spot them. The best information technology could find was someone else's confront with a 62 percent similarity. Apparently, my pictures do not appear on i of the 10 million sites analyzed by PimEyes.

Note that PimEyes offers a 24 hour deal that unlocks access to its premium search results. Just given my questionable results, I would non recommend paying for this service.

5. Betaface: Facial Recognition Demo

Betaface offers a facial recognition search similar to PicTriev's photo identification. You lot can upload an image or send the image URL and the confront search engine will isolate and characterize all the faces it can place in the photograph.

Betaface photo metadata

Next, you lot can compare faces (with other images you uploaded), search celebrities, or search Wikipedia for each recognized face. The results volition appear in theFace up recognition matches tabular array.

Betadata face recognition matches

This tool is useful for uploading and comparison photos in majority. In addition to classifying faces based on 101 pro facial points, y'all can likewise enable extended geometric and colour measurements, as well as a "all-time confront only" feature. Both of these slow downwards the processing, but will increase the quality of your matches.

Bonus one: How Normal Am I?

A face print taken with the How Normal Am I test.

Practise you wish you were special? This narrated AI feel demonstrates how algorithms judge your age, gender, attractiveness, emotions, BMI, life expectancy, and more just based on your face. If you're willing to expose your face up through your webcam, this is a fun experiment.

I took the exam twice. The results were quite incorrect both times. The first time, the algorithm idea I was a man and gave me a 33 percent normal score. The 2d time, it correctly judged me every bit female and gave me an xviii percent normal score. Go figure.

This art project was developed by Tijmen Schep using funding from the European Wedlock. Read the terms and conditions to find out how your data will be used.

Bonus 2: Everypixel Historic period Recognition

Age recognition via a photo using Everypixel's API.

This tool uses a photo to guess the subject'southward historic period. It's a machine learning API demonstration that besides covers other details AIs tin can learn from visuals, such as the discipline's gender, happiness, race, education, or occupation. While its guess that I look 27 in the photo is quite flattering, information technology's manner off. It as well guessed with 58 percent certainty that I'm Caucasian, and 46 percent certainty that I was wearing spectacles. Well?

Microsoft used to offering a like tool and learned some fascinating details. Apparently, wearing a hat can make you look younger, while glasses will brand you lot look older, and losing your beard can also shave off some years.

You lot can learn more about machine learning past using Microsoft Lobe.

What Does Your Face up Reveal?

Face recognition and search tools have a range of useful applications. Not only can they aid the constabulary identify suspects from security camera footage. They tin also help professional photographers or media companies index visual fabric and build big and easy to search athenaeum. Moreover, confront recognition tin supervene upon passwords and keys.

But at that place'southward a dark side to every tool. Non as well long agone, the Facezam viral marketing scam highlighted what confront recognition could do to your privacy. The creators of the app claimed that—within seconds—y'all could find anyone's Facebook profile by uploading a picture of their face. Essentially, FindFace for Facebook.

While such an app violates Facebook's privacy policies, Facebook itself uses facial recognition powered search to place people in photos (unless yous disabled the feature). And presumably, Facebook's face search engine is better than the FBI'southward identification tool.

Why? Because you've been voluntarily stuffing Facebook's database with a huge multifariousness of photos, all helping its AI meliorate faster than the FBI could ever dream of. And information technology'south all legal. You can't e'er hide your face, but you can protect your privacy online.
