The technology continues to amaze us with more developments and the recent and the most exciting of all of them is this Face recognition.
 

Face detection does not only works for screen locks and security but there is something more to it. The Face detection software solution involves identifying human faces in digital images and videos and then the AI starts working on it and will give us complete details about the face. These details include information like size, location, and pose of the person. Yes, this has been the recent development in the Facial Recognition Technology (FRT).
 

Face Detection Software Solutions
 

So, this all has been possible because of the amazing Face detection software tools that came into being. Now, it has become a billion dollars industry and this is just the beginning. There will be a lot coming in soon. So, in this article, we will talk about the significance and implication of face detection technology in various industries and how different face detection software actually works. We will also be discussing different free and open-source software solutions available in the market.
 

So, let us dig in and get some useful insights about face detection software and technology:
 

The face detection technology has surpassed ordinary uses paradigm and is working on solutions that we could never imagine. Yes, these face detection software tools actually analyse the characteristics of the facial images of a person that were taken using a digital video camera. The latest of which we can talk about is the Airport security wherein the CCTV cameras check the pictures and match them with the passenger’s picture in the passport. The tool behind this is the pattern detection technology and the algorithms tell if the image matches or not.

So, there are different technological methods employed for doing this:
 

face detection methods
 

-> Knowledge-Based: The basic principle guiding the structure of a face like a face must have a nose, eyes, and a mouth at defined distances which makes up to recognizable facial features.
 

-> Feature-Based: This method focuses more on the particular features of the face.
 

-> Template-Matching: This method uses parameterized or pre-defined face templates for face detection.
 

-> Appearance-Based: This method depends upon a set of face models and is also used in feature extraction for face recognition.
 

Now, there are different uses of face detection software in various industries and sectors. Mostly, what it is being used is for facial biometrics for security and employee data storage. Yet, there are still many more uses of the same that are coming in the picture.
 

a). Payment industry- Can you imagine making payments by just showing your face to the screen? Well, if you have not thought of it yet, it is time you get ready to be amazed by this. New selfie pay apps are coming in the picture where the payments will be confirmed by just bring the phone close to your face without eve using their credit/debit cards for online shopping. The face detection and recognition devices have also been installed at shopping stores and ATMs.
