A human face contains a set offacial features unique for every person in the world. These features (alsocalled facial landmarks) are locations of the eyes, nose, mouth, and distancesbetween them. Phototheca utilizes face recognition technology based on artificial intelligence, which can extract those facial features from a photo and build a unique faceprint of a face. Then Phototheca can compare faceprints of every found face to each other and recognize if faces on different photos belong to the same person.
Phototheca scans each photo in a library, looking for visual landmarks of a face to detect a face and get a bounding box of it. Phototheca analyzes facial features of every face, such as locations of eyes, nose, mouth, and distances between them.
The unique combination of their measurements creates a faceprint of a face. Then Phototheca compares every faceprint to each other and understands if faceprints belong to the same person(or not).

Phototheca collects photos of persons into stacks and gives a way to assign a name to a person. When a name is assigned, all faces of a person are marked with a provided name automatically.
Using AI face recognition technology, Phototheca can automatically match the faces of the same person, even with different lighting and shooting conditions, different poses, and ages.
How is Face Recognition Done?
Recognize, collect, tag, and sort all faces of your beloved easily with Phototheca. Phototheca offers a free time-unlimited trial to see how facial recognition search works for your photo collection. Phototheca does not upload photos from your PC to a cloud ever. All facial recognition is performed on your PC only. All calculated faceprints reside on a local PC and are never transmitted to any clouds or web storage. This article will reveal the most critical aspects of the best face detection software systems and their importance in various industries.
This article aims to help you understand howuseful free and open source face detection tools are in today’s competitive market environment.
Let’s have a look at them in detail. OpenBR is a free face detection software that supports the development of open algorithms and reproducible evaluations. The stable version 1.1.0 of the software was released on September 29, 2019. It operates on Windows, Linux, OS X, and Raspbian based operating systems. The project is licensed as per Apache 2.0. OpenBR exposes a C++ API that can be embedded into one’s own applications. It is a complete NIST compliant software that evaluates facial recognition, detection, and land-marking. It implements the 4SF2 algorithm to perform face recognition.
The software algorithms also work for age estimation and gender estimation. As one of the leading facial recognition programs – OpenFaceTracker detects one or several faces on a video or a picture and identifies them through a database.
It is an open source face detection tool that comes with an lGPLv3 license and stable version 3.0. The invention of the software is inspired by the American TV show ‘Person of Interest.’. Can fetch and process real-time images followed by identification, stock, and available print data. It requires Open-API for deployment and can operate on a Windows-based system.

The software needs OpenCV3.2 and QT4 to be installed on your computer before installing OpenFaceTracker software. OpenFaceTracker software is developed as a modular library. Hence, it can either enable or disable some part of the software. Open Biometrics Initiative is an open-source software from ImageWare systems. It is a face detection software for PC that works on 32 and 64-bit Windows and Linux, and now, its beta version is also available. It is written in C++, C, and Java and holds Apache License V2.0. The initial version of the software was released in April 2010.
It is an open specification system that is used by government agencies for the management of biometric data. The software includes two open-source APIs: OpenEBTS API and OpenM1 API.
The downloadable source code for the software is managed as per OBI. If you are already using one of the software solutions listed above, you can freely share your reviews here. It has been ten fruitful years since the very first face detection software for PC was invented that can detect and recognize human faces. Now, a market full of face detection software solutions and programs are available for individual and business uses all over the world.
Do the sharing thingy. Facial recognition search technology has come a long way in recent years.
Combined with facial identification technology, face recognition technology not only allows software to recognize when a face occurs in an image, but to also identify other images with the same face or even confirm an identity in real-time.
The applications for this kind of tech are vast – from checking to see if anyone is using an image illegally to unlocking your phone. For photographers, it does everything from in-camera face detection to instantly pulling up every image in your library pertaining to a particular person. If you’re an event or portrait photographer, automatic face tagging can save you incredible amounts of time. For hobbyists who love family photos, facial recognition technology can make finding photos of loved ones infinitely easier. When used in a reverse image search, face recognition can also be used to see if anyone has taken your images without permission, violating copyright.
Let’s take a look at how it’s done and how best to use it. There are two different types of facial recognition – fiducial recognition and pixel detection. In fiducial recognition, the software measures the dimensions of different facial features.
How facial recognition works?
Examples include the distance between the eyes, the width of the nose, the length of the jawline, or even the shape of the cheekbones. Pixel detection analyzes the pixels in an image and compares them to a database of appearance generalizations (i.e.
age, sex, etc.). Both methods collect biometric data from a person’s face and facial expression and use this to identify and/or verify the identity of the person in the photo. Paired with artificial intelligence and machine learning, face recognition technology has become more and more accurate, and now can even work with incredible accuracy in real-time – at least in certain demographics.
A reverse image search is the process of uploading a photo into a search engine and directing it to find similar images. This can be anything from people to car parts to plant IDs. The search results will not only show similar images but also websites that have that image or ones similar to it.
