A face isn't quite as unique and ageless as a fingerprint, but it'southward hands 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 end of the spectrum, a face search tin reveal your online (celebrity) lookalikes or your age.

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

Did you know that you could search Google past images? Rather than a keyword, yous can employ an prototype to search for similar images.

Click the camera icon to search by image. You can either paste the image URL or upload an image and Google will notice similar images.

Moreover, you can make Google search for faces only by adding a small bit of code.

When you go to Google Images Search, enter your query, hit Enter, and then add "&imgtype=face up" (without the quotes), either to the end of the search URL or right before another string starting with &. This volition further improve the results of your confront-related search.

In one case you add the image blazon to the URL, you'll also observe this option under Tools > Type.

Google also offers its face recognition in Google Photos, significant you lot tin search your photos for people and even pets.

2. PicTriev: Face Recognition

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

What you practise is add the URL or upload a photo in JPG or JPEG format, with a size no larger than 200 KB, and the search engine will return matching celebrity images constitute 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 historic period interpretation of xxx, yet, is very flattering.

Information technology works much better if you search for a celebrity prototype.

TinEye reverse image search engine works for faces.

TinEye'southward reverse image search works almost like Google. You can upload an image or paste a URL and search for it. TinEye does non back up any more search operators, making it both simpler and basic.

In my test, TinEye found three results, one of which Google had not included because the site died years agone. Also, it missed a newer upshot that its large brother had picked up. To me, this indicates that TinEye'due south search index is largely outdated.

Unlike Google, TinEye links directly to the pages where it plant the images and it skips like images.

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

For example, you can search for Jennifer Aniston's face using four unlike photos at once. PimEyes will observe the original photos, as well as other shots of Aniston.

Curiously, while the app does find the original pictures used for the search, the similarity is just scored at effectually seventy percent. Shouldn't information technology be closer to 100 percent? Or does the algorithm have image resolution, size, effulgence, and other digital alternations into business relationship?

PimEyes facial matching

I tried the service myself, providing PimEyes with 3 different photos of me to analyze.

There are other photos of me to exist found online, but PimEyes didn't spot them. The all-time it could notice was someone else's face with a 62 percent similarity. Apparently, my pictures exercise not appear on one of the ten million sites analyzed past PimEyes.

Annotation that PimEyes offers a 24 hour deal that unlocks access to its premium search results. But given my questionable results, I would not recommend paying for this service.

v. Betaface: Facial Recognition Demo

Betaface offers a facial recognition search similar to PicTriev's photo identification. You can upload an image or send the paradigm URL and the face up search engine will isolate and characterize all the faces information technology can identify in the photo.

Adjacent, you can compare faces (with other images you uploaded), search celebrities, or search Wikipedia for each recognized face up. The results will appear in theFace recognition matches table.

This tool is useful for uploading and comparison photos in bulk. In improver to classifying faces based on 101 pro facial points, you can also enable extended geometric and color measurements, likewise equally a "best face only" feature. Both of these slow down the processing, simply will increment the quality of your matches.

Bonus 1: How Normal Am I?

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

I took the exam twice. The results were quite wrong both times. The first fourth dimension, the algorithm idea I was a man and gave me a 33 per centum normal score. The second time, it correctly judged me as female person and gave me an 18 pct normal score. Get figure.

Bonus two: Everypixel Age Recognition

Age recognition via a photo using Everypixel's API.

This tool uses a photo to guess the subject's age. Information technology'southward a automobile learning API sit-in that also covers other details AIs can learn from visuals, such as the subject'south gender, happiness, race, education, or occupation. While its approximate that I wait 27 in the photograph is quite flattering, it'southward way off. It also guessed with 58 pct certainty that I'yard Caucasian, and 46 pct certainty that I was wearing glasses. Well?

Microsoft used to offer a similar tool and learned some fascinating details. Plain, wearing a lid tin brand you wait younger, while glasses will make you look older, and losing your beard tin can also shave off some years.

Yous tin can acquire more most automobile learning by using Microsoft Lobe.

What Does Your Face up Reveal?

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

Just there's a dark side to every tool. Not too long ago, the Facezam viral marketing scam highlighted what face recognition could do to your privacy. The creators of the app claimed that—inside seconds—you could discover anyone'southward Facebook contour past uploading a picture of their face up. Essentially, FindFace for Facebook.

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

Why? Because you lot've been voluntarily stuffing Facebook'southward database with a huge variety of photos, all helping its AI improve faster than the FBI could ever dream of. And it's all legal. You can't ever hibernate your face, but you tin can protect your privacy online.
