We are discussing the applications of face recognition software and the best open source and free face detection software systems currently!

Facial Recognition software makes it easy to add accurately analyzed images and videos to your applications. It thus becomes important to understand how facial recognition works and is utilized in wake of many technological advances.

Let’s Understand Facial Recognition

It is a system to identify a person via their facial expressions, image, or video. It can be anything – a human, an animal, any object, or a place etc. The reason it has become popular these days is due to the presence of millions of mobile applications which require filters and attributes to bring that uniqueness to their offerings. Attributes such as smiling face, closed eyes, red hair colour, face with glasses, the crown on head, bald head, long hair, age range help in identifying a person using a source image or a unique identifier.

Applications of Facial Recognition

This feature is used across industries acting as a secondary authentication for mobile applications, provide identity verification, without any human intervention. This technology is helping news organizations identify celebrities in covering significant events.
Any application of facial recognition has to be in coordination with the individual’s rights, their right to privacy and abiding their autonomous decisions for scenarios that require analysis by a human. In the case of a financial institution, they should clarify their use of technology and ask for customer approval of the terms and conditions.

How does Facial Recognition Work?

The face detection software recognizes and matches the faces based on their visual geometry which includes the relationship between the eyes, nose, brows, mouth, and rest of the facial features. As face tracking software analyzes the image, an outline is created around the face which is known as a bounding box and this determines the only part of the image under observation. In the next step, object notation numbers that indicate the “location” for the major elements of the face are produced. As the customers look for a particular face, the underlying face detection technique compared that data from the source image to each of the images it searches. Then a similarity score is assigned to every face that is recognized. Such face determining software must ensure that the information that they hold or capture does not contain any details regarding an individual’s identity, just that the one face is a potential match for another.

Then a similarity score is assigned to every face that is recognized. Such face determining software must ensure that the information that they hold or capture does not contain any details regarding an individual’s identity, just that the one face is a potential match for another.

What is the Similarity Score/Threshold?

Similarity Score

It is a statistical analysis or measure of how well the two faces in an image are likely to match. The more the similarity score, the better are the chances that the face recognition tool was able to analyze maximum similarity with the face being searched for. The more the percentage, then it is more likely that the two images are from the same identity. But sometimes, even a 99% similarity does not guarantee that it is a positive match. This is based on a probabilistic system, where determinations are not always precise and accurate but a prediction.

Similarity Threshold

It’s the opposite of the similarity score, where the lowest similarity score or the least willingness for the two images to match has a fundamental impact on the search results that are returned. Normally a 99% threshold setting for use cases is important for high accuracy. The threshold setting is directly proportional to the number of misidentifications/false positives that can be afforded by the customer. A setting that suits the applicability can be selected. This poses to be a basic first step by the law enforcement scenarios.

What is Celebrity Recognition/Detection?

It is specially designed to identify potentially famous people. But celebrities often come across in different get-ups, makeups and hair-dos so the face recognition software has to be designed on pre-labelled data to return the highest probable matches within a specific list of famous people. This approach allows for a higher number of false positives but must not be used in wake of public safety and aligned laws. Open source facial recognition software must be designed to give the precise amount of details about the similarity between two faces and must be optimized for precise matches and used in security and public safety applications.

Is Facial Recognition Safe?

As we have discussed enough the limited use of facial recognition software in adherence to public safety and laws to protect people’s privacy, let’s discuss some misconceptions that people, in general, might have regarding facial recognition tools and how these work.

• These cannot match faces to photos better than machines.
• The existence of false positives (to an extent) never completely means that facial recognition is flawed. If better settings are applied, then a reasonable similarity threshold can be reached, that co-relates with the given use case. Often, such false positives can be reduced over some time as the technology is improvised.

Can We Report in Case of Potential Abuse by Facial Recognition Software?

Yes, in case you suspect that the facial detection tool is being used in a manner that is abusive or illegal, or infringes the rights of the public, it should be reported to concerned authorities or the consumer rights department.

Key Features of Face Recognition Software

Basic face recognition software will include:

• Labels: Identification of thousands of varied inanimate objects and non-living structures like a statue, a building, a telephone, a football etc. or to identify any specific activities like delivering a package or running and likewise.
• Customizing Labels: This includes identification of your products on the shelf, identification of your brand logo on any of the products, classification of your machine parts in an assembly line, detecting your animated characters in videos etc.
• Moderating the Content: This helps in the identification of potentially dangerous or inappropriate content across images/video assets and simultaneously provides you with detailed labels so that you may control what you wish for with your image recognition software.
• Detecting Texts: This includes identification of some kind of skewed or distorted text to capture details like store name, brand name, street signs, any forced narratives, product packaging etc.
• Face Detection and Analysis: This includes detecting any face that appears in the image or videos, and extract attributes like gender, age, open/closed eyes, frown/laughing/happy/sad facial expressions. This is particularly useful when directors at movie studios need to create a timeline of emotions expressed by an actor.
• Searching and Animating Face: This includes providing a fast and accurate search which allows identification of a person in a still or motion image using a private repository of face images. The required identity can be analyzed by comparing various images.
• Recognizing a Celebrity: face detailing software comes preloaded with image and video libraries that have catalogue footage and photos for marketing, advertising, media industry use cases.
• Detecting Personal Protective Equipment (PPE) Detection: Image detection software is more relevant these days as they can help recognize images from your on-premises cameras at scale to automatically detect if persons in images are wearing personal protective equipment (PPE) such as face covers (face masks), headcovers (helmets), hand covers (gloves) and whether the protective equipment covers the corresponding body part like a nose for face covers, hands for hand covers, head for head covers etc.

Applications and Use Cases of Face Recognition Software

• Media Analysis: Face Detection Software helps in streamlining media tasks by automating the detection of frames, end credits, colour bars, shot changes etc. This helps in reducing costs and associate workflows like video ad insertion, content production, and content operations.
• Make Content Discoverable: This includes extracting metadata from the images and video files, capturing objects, texts, faces and more and using it to determine the right content that you’re looking for.
• Flag Inappropriate Content: This feature will flag inappropriate content (graphics, text, use of weapons, nudity, violence, in any form) and you may create your own rules based on what you consider appropriate for your audience.
• Enabling Digital Identity Verification: These enable scalable authentication to automate payments and other scenarios to verify identity. It involves comparing a clicked photo with the photo printed on any of your documents.
• Safety At Workplace: Face detection software is also deployed to automate the detection of Personal Protective Equipment (PPE) at scale to improve workplace safety practices and to better comply with health regulations and occupational safety.

How Can Face Detection Software Make Our Lives Better?

Facial Recognition Technique is now everywhere from airports to traffic cameras. And it doesn’t stop there. Government agencies aren’t only building and using facial recognition. Amazon has created a real-time technology called Amazon Rekognition (Real-Time and batch video analytics), and they are actively selling that video to law enforcement. As of now, this technology is not being used for investigative purposes; facial recognition is used for good as well. Experts at Oxford University have created some techniques with facial detection software that works for humans as well as for chimps. It can recognize animal faces in as quick as 30 seconds. These tools can make researching animals in their natural habitats much easier. Facebook uses this feature in a way to automatically tag people in photos. This feature can be turned off. Facial Detection Software is often attached to toilet paper dispensers. The dispenser will deny the same person any extra squares if they try again within 9 minutes.. (can’t spare a square). From Shanghai Airport to Movies to Tissue Dispensers to Government Agencies to Police Surveillance, facial detection software has probably become an important part of identity detection (with privacy intact).
