Data acquisition in face recognition

  • How are databases involved in facial recognition?

    Face Databases are imagery data that are used for testing face processing algorithms.
    In the contents of biometrics, face databases are collected and used to evaluate the performance of face recognition biometric systems..

  • How does facial recognition collect data?

    Facial recognition uses technology and biometrics — typically through AI — to identify human faces.
    It maps facial features from a photograph or video and then compares the information with a database of known faces to find a match.
    Facial recognition can help verify a person's identity but also raises privacy issues..

  • What are the data concerns with facial recognition?

    Unlike many other forms of data, faces cannot be encrypted.
    Data breaches involving facial recognition data increase the potential for identity theft, stalking, and harassment because, unlike passwords and credit card information, faces cannot easily be changed..

  • What data does facial recognition collect?

    Key factors include the distance between your eyes, the depth of your eye sockets, the distance from forehead to chin, the shape of your cheekbones, and the contour of the lips, ears, and chin.
    The aim is to identify the facial landmarks that are key to distinguishing your face..

  • What is data acquisition in face recognition?

    Basic Blocks of Face Detection System .

    1. Face acquisition phase: In the initial phase, the image is captured by means of any source such as camera or working with standard databases of images.
      2. The captured image is converted to gray scale image and resized to eliminate pose problem.

  • Face Databases are imagery data that are used for testing face processing algorithms.
    In the contents of biometrics, face databases are collected and used to evaluate the performance of face recognition biometric systems.
  • The data may come from a range of local, national, and personal sources.
    In conclusion, the most accurate answer is that the data in facial recognition databases usually come from a combination of local, national, and personal sources.
  • Unlike many other forms of data, faces cannot be encrypted.
    Data breaches involving facial recognition data increase the potential for identity theft, stalking, and harassment because, unlike passwords and credit card information, faces cannot easily be changed.
In face recognition research, the acquisition of three-dimensional face data is the first step, and the quality of the acquired data directly affects the follow 

Can 3D facial data improve the accuracy of facial recognition?

The geometric information provided by 3D facial data could significantly improve the accuracy of facial recognition in the presence of adverse acquisition conditions.
However, the lack of a 3D facial recognition database hinders the exploitation of methods based on deep learning.

Occlusion

Occlusion can be defined as the hindrance or blockage of a particular section of an image or object.
Hence, occlusion of the face image can be described as when part of the face is covered or obstructed either intentionally or unintentionally, thus resulting in a reduction of the performance of the face recognition system [66, 100].

Plastic Surgery

It is observed that face recognition techniques fails to identify individual’s faces after the process of plastic surgery.
This is a situation where the face image of an individual is entirely changed, thus changing to an entirely different individual [64].
The plastic surgery process on the human face introduces change in skin texture between imag.

What is a face recognition acquisition device?

Face recognition acquisition devices can be a 2D, 3D, or infrared camera or a combination of these modalities.
Pre-processing can detect facial landmarks, align facial data, and crop the facial area.

What is face recognition method based on?

After years of continuous exploration and research, face recognition has made some achievements in the following directions:

  1. face recognition method based on relative difference space
  2. face recognition method based on local
  3. face recognition method based on global
  4. face recognition method based on subspace
3.
Method 3.1.

Why do we need a face recognition dataset?

The importance of creating face recognition datasets is essential, first, for security-related applications, and second, to allow the development and validation of methods based on deep learning in 3D facial recognition.
