How to do face detection in Matlab?

Face detection using MATLAB system testing

  1. Install MATLAB version R2012a or higher version in your system.
  2. Download the source folder.
  3. Check the device ID, as shown in Fig.
  4. Run the program.
  5. Click on Start button to initialise camera settings.
  6. Next, click on Face button and the camera will detect the face.

What is Matlab in face recognition?

MATLAB has the vision. CascadeObjectDetector system object, which has the viola-jones algorithm used detect faces/objects and it is found in the computer toolbox. The cascadeObjectDetector can be used to detect people’s faces, nose, eyes, mouth, and upper body.

How do you detect a face in MATLAB?

Before we start tracking a face, we should be able to detect it. In Matlab, we the vision.CascadeObjectDetector () to detect the location of a face in a video frame acquired by a step () function. It uses Viola-Jones detection algorithm (cascade of scaled images) and a trained classification model for detection.

How are face recognition algorithms used in MATLAB?

The vision.CascadeObjectDetector makes use of the Viola-Jones algorithm for the identification of faces, eyes, mouth, nose, or the upper body. A custom classifier can be trained by using MATLAB’s Image Labeler and used along with the System object.

How is face detection used in security systems?

Face detection is the process of identifying one or more human faces in images or videos. It plays an important part in many biometric, security and surveillance systems, as well as image and video indexing systems. This face detection using MATLAB program can be used to detect a face, eyes and upper body on pressing the corresponding buttons.

Which is the best algorithm for face detection?

Viola-Jones algorithm is an object recognition framework that allows the detection of human faces. Viola-Jones algorithm is robust, powerful, and faster despite being outdated. In this article, we will look at how to use the Viola-Jones algorithm to detect faces in real-time. Have Matlab installed on your computer.
