• Find face photo search program. Search a page by photo

    FindFace service, developed for users of Russia's largest social network VKontakte will be able to find any person in the virtual space with just one photo. The project is based on facial recognition technology created by N-Tech.Lab.

    FindFace allows you to find a person, find out open information and contact him through a social network account, and for all this a photograph taken mobile phone. Poor lighting or a bad angle will not prevent the algorithm from quickly finding the right person. The service identifies the person in the photo with an accuracy of about 70%, and if the right person was not found, FindFace suggests looking at the photo similar people, which makes it unique among modern dating services.

    New look social service was developed based on technology from N-Tech.Lab, a company specializing in solutions in the field of neural networks. Such networks are capable of analyzing information and learning like humans, but they do it much faster. To search the desired file in a database of 300 million photos, the N-Tech.Lab algorithm takes less than a second. This solution was recognized as the best at the international competition The MegaFace Benchmark, organized by the University of Washington.


    Now you can use FindFace using mobile applications for iOS and Android, as well as through the browser. All necessary calculations are performed on remote servers, so the requirements for gadgets are minimal. The service allows you not only to find the desired user, but also send him messages, like, view photos and other information.

    At the first stage of its development new service will work on the VKontakte social network, whose daily audience exceeds 100 million people. In the future, FindFace will become available to users of other social networks.


    Basic functionality is free. For users with a wider range of capabilities (unlimited number of queries per month, complex search settings, etc.), the service will cost from 149 to 459 rubles per month.

    Thanks to the availability of special web services and applications, you can easily find a person by photo.

    Majority modern programs and websites use artificial intelligence technology.

    It allows you to increase the accuracy of facial recognition in a photo as the number of program users increases.

    It should be understood that no search engine can give a 100% guarantee of finding an image. Often errors occur when reading pixels, or the browser searches for photos that are similar in meaning and color palette.

    Below are some of the most effective ways. If one of them does not help you, feel free to move on to the other.

    Ultimately, one of the methods will turn out to be the most suitable for your picture and the person will be found. We also recommend that you carry it out using several photographs at once, if you have them.

    ServiceGoogle

    The first and easiest way to search by image is the well-known Google. Developers popular system introduced a function for working with user images.

    Now you can not only enter a query, but also insert individual images into the text field. The search engine carries out analysis for all sites and social networks that are indexed in the system.

    Let's look at simple example how to use the function:

    • Let's go to the website. This page differs from the standard one in the presence additional button to add;
    • To get started, click on the camera icon. A window for selecting the type of photo upload will appear. The user can provide a direct link to an image already posted on the Internet or download graphics from the computer’s memory;
    • Click on the “Search by image” button.

    The result of processing your request in Google will look like this:

    It will automatically indicate the person's name or subject. Also, the user will be able to view similar images. One more element search results– pages that have a mention of the person found.

    Often, the result only shows similar images without providing a name. This means that on the Internet similar pictures too many and the system cannot find a 100% exact match. Try scrolling down to the "Pages with matching images" box. This way you can view a list of links that contain what you are looking for.

    With it you can search not only for people, but also for various objects. As practice shows, a search engine can be very useful when you need to find out the name of an unknown object or find things you like.

    Yandex

    Photo search from Yandex is another popular service, which searches for graphic content across all sites. At first glance, it is practically no different from Google, except for the interface and design. However, Yandex developers claim that their system uses a modified algorithm using computer vision.

    This way, by using both systems, you can have a better chance of finding the one you're looking for. To start the analysis, go to the main site. Find the text line and next to it click on the “Pictures” tab to go to the corresponding section:

    • In the tab that opens, click on the camera icon;
    • Now in the tab that opens, click on the button to load a photo from the PC memory or provide a direct link to the picture on the Internet. Click on “Find”;

    The result will be a set of maximum similar images, with the help of which you can find a person. Also, you can choose different sizes pictures and continue analysis with photos best quality. Be sure to look at the list of mentions on other sites to increase your chances of discovering the person.

    Analysis by photo inVK

    Besides standard systems, there are a lot of services for monitoring by photo only on specific social networks. Since 95% of Runet users have a profile on VKontakte, it is better to search for it using special resources, which work only with this social network. This way, you will reduce the analysis time and the number of similar pictures.

    To start monitoring photos in VK, you need to install an extension for Chrome browser. The app is called "StopFake". Go to the software store and enter the name of the extension. Then click on the install key and wait for it to appear on the right top corner buttons.

    Although the program is designed for quick definition fake accounts, it can also be used to search for people. You will need to upload a photo to your album on VKontakte, since this can only be done using the one that is in the site’s database.

    • Open the photo in your VK album. The album can be private, the main thing is that it is on the website;
    • After opening the image, press the key to launch the StopFake extension. It is located in the upper right corner of the browser toolbar. To eliminate possible errors in the operation of the utility, we recommend restarting the browser immediately after installing the extension;
    • It will automatically identify them on the social network that contains the photo you are looking for. Thanks to the author's signature, you can easily find the person you need. Click on the author's name to go to it.

    In recent times, facial recognition programs have been exclusively in the service of government agencies. They help identify a person based on facial features. Now the use of such software most often seen in security systems, in commercial activities related to advertising and promotion of various services.

    Also some semblance of these online services and programs are also available for ordinary users, they can be found on the Internet. An example is Lenovo program Veriface. This is a proprietary built-in utility that allows you to unlock your device by analyzing your face.

    How does face search work?

    In some services, search by faces works on based on neural network technology. The search is based on certain basic features: image weight, resolution, color correction, exposure, resolution, etc. Nowadays, neural network technology is developing, in addition to the basic characteristics, the definition occurs using additional features : skin texture, shape of mouth, ears, hair color, eye location, etc.

    To find similar person, you must upload clear photos, otherwise the search will fail. It is also worth saying that social networks protect information about their users. Most social networks have built-in profile protection features that allow you to hide a person’s photos.

    Facial recognition programs

    Facial recognition systems (programs) from photos and videos use more advanced algorithms. Similar systems no in open access , they are used in security services, to control and prevent emergency incidents in large cities and in crowded places.

    Such software most often uses the Viola-Jones recognition algorithm. The program, using this method recognizes faces even when rotated 30 degrees. Method based on Haar characteristics, which are a set of black and white masks of various shapes and sizes. Masks are applied to the image and pixel brightness is calculated by adding, after which the difference in values ​​is calculated.

    Next, the system compares the results with the accumulated data, and having identified the face in the image, it continues to track it to select the optimal angle. After this, the reading process starts and the software finds reference points on the face. Next, the image is analyzed with the data that is in the databases. If they match, the person is identified.

    FindFace

    One of the most available methods Finding a person is a search on social networks, including VKontakte. You can search using different parameters, it all depends on what data you have. There are two ways to find the page you need by photo.

    You have an image and, based on it, you need to find the person’s page. It should be said that for a successful search, the photo should not be covered by the user’s settings. In this case, attempts will not yield results.

    Another problem is the lack of photography as such on the Internet. Some people prefer to bet beautiful pictures instead of your photos. Therefore, the search becomes more difficult.

    To find a user by photo:

    1. Log in to your VK account;
    2. Upload an image to your profile;
    3. Click on the picture to open it in full size;
    4. In the line where the page address is written, select the photo id and copy;
    5. Click on the News tab (in the column on the left);
    6. In the folder that opens on the right, select “Photos”;
    7. Place the cursor in the search bar and enter “copy:id from image”;
    8. Click search. The system will display all the results found. There may be a lot of them or none at all.

    If there are many matches, you will have to check each of them. To do this, select a photo and, by clicking on it, see who posted the image. In this way you check everything until you find what you are looking for.

    Please note that there are fake pages, so-called fake profiles. When accounts are deliberately created with names and photographs real people. This is done mainly for the purpose of fraud.

    Through browsers

    Any browser has the ability to search for images and photos. When using them, the system searches for matches across the entire existing database, and not just in the VK social network. To get started, open your browser. The principle is the same everywhere, consider an example with using Google Chrome.


    If you didn’t find the account you were looking for with such a photo, then it doesn’t exist or the photo is in a closed album.

    In another browser, follow the example above. The algorithm is the same, only the interface may differ.

    In Yandex browser, select home page Pictures tab.

    Next, enter the path to the image you saved and click “Find”. Sometimes this way you can already see deleted photos in contact. And even pages. If your search is unsuccessful, do not be discouraged.
