The Best 8 Free and Open Source Face Detection Software Solutions

Technology never ceases to amaze us. Pattern recognition and image processing is one area that has been in huge discussion and research these days. The evolution of the biometric authentication solutions offered an antidote to inconvenient, clunky, and easy-to-forget passwords. It helped the enterprises, schools, community homes, offices, and residential areas to keep their premises protected using the right security technology. Face detection is one among those prominent biometric solutions that involve identifying human faces in digital images and videos. Once the face is detected, the AI then provides the information on its size, pose, and location. All this is backed-up by the advanced best face detection software tools and facilitated as per the algorithms of Facial Recognition Technology (FRT).

The concept came into context in the year 2001, when Paul Viola and Michael Jones introduced the object-detection framework. The framework aimed at detecting objects in real-time, and the problem of face detection primarily motivated the outcome of the required solution. Today, the Facial Recognition Software Market is likely to touch USD 11.30 Billion by the year 2026.

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 how useful free and open-source face detection tools are in today’s competitive market environment.

Face Detection Technology

The fastest biometric-based face detection technology comes with the only purpose, i.e., to identify human faces. Today’s face detection and recognition systems are far better than the fingerprint readers and eye scanners. These systems analyze the characteristics of the facial images of a person that were taken using a digital video camera. For example, the CCTV cameras installed at the security check area in an airport can trace the record of matching photos of every passenger attached to the passport with their faces.

Face Tracking

How does Face Detection Technology work?

The state-of-the-art face detection software uses pattern detection technology. No personal data is collected, and no images are stored.

The algorithms decide whether an image is either positive or negative. The application that confirms this state of the image is called a classifier. While detecting a human face, the technology returns to coordinate the locations of the exposed face within a video or an image with a bounding box.

Face Detection - Bounding Box

What are Face Detection Methods?

Experts have classified the face detection method into four categories. The below-given diagram will help you understand more in this regard:

Face Detection Methods

  1. Knowledge-Based: Human knowledge to detect the face, i.e., a face must have a nose, eyes, and a mouth within certain distances and positions with each other.
  2. Feature-Based: This method helps in locating faces by extracting structural features of the face. The idea behind this is to overcome the limits of the instinctive knowledge of faces, and it holds a 94% success rate.
  3. Template-Matching: This method uses parameterized or pre-defined face templates for face detection, establishing a correlation between input images and the templates.
  4. Appearance-Based: This method depends upon a set of face models and is also used in feature extraction for face recognition.

Promising Applications of Face Detection Technique

Facebook started inputting automatically generated tag suggestions for all the pictures that are uploaded by the users to the platform. Facebook Company uses a simple face detection algorithm to analyze pixels of images having faces and compares it with the relevant users as if the face matches. Here are some applications that involve promising usage of face detection technology:

Applications of Face Detection Technology

How Face Detection Applications are Useful for Businesses?

Many manufacturing, construction, design, law enforcement, financial, and healthcare industries and businesses are gradually applying facial biometrics to protect their physical and digital possessions.

  1. Payments – FaceTech doesn’t even need customers to use their credit/debit cards for online shopping. MasterCard also introduced a new selfie pay app in 2016 to confirm a payment using their camera. At shopping stores and ATMs, face detection and recognition devices are already installed.
  2. Security and Access – Facial biometrics can also be integrated with physical objects and tools in addition to verifying a payment. Innovative facial security measures are useful for handling sensitive data of a family or organization and keep tight control over whoever is entering their facilities.
  3. Criminal Identification – Face detection applications in combination with Machine Learning (ML) algorithm helps in identifying the suspects from people’s driver’s licenses, merchant licenses, delivery service licenses, and so on.
  4. Advertising – Marketers and advertisers collect and collate the personal data of the masses to target their customers. The best face detection software systems allow companies to recognize specific demographics. For example, a male between the ages of 12 to 21 will get the ad on his mobile screen displaying the latest FIFA game. Many experts assume that cameras could change the face of retail, but only if they correctly identify the customers.
  5. Healthcare – This sector has two advantages of using face detection technology. The first is to secure the patient data by using a unique photo of the patient, instead of usernames and passwords. The second is to identify illnesses by checking out the features of the patients. It helps in slashing long waiting lists and streamlining the appointment process.

Undoubtedly, these applications suggest how useful the face detection technique is to accomplish several jobs and in a variety of fields.

Now, let us check the top-rated free and open source face detection software solutions that most businesses prefer today.
