Special Issue Information

Dear Colleagues,

The popularity of smart gadgets and the advancement of camera capabilities have resulted in the concept of facial recognition becoming a hot topic among academicics and practitioners. Facial recognition is a way of recognizing a human face with the help of a computer vision algorithm. Traditionally, facial recognition algorithms are mainly employed in the surveillance system but nowadays have been expanded to other fields including entertainment, e.g., Snapchat.

Emotion detection has been the most challenging and yet interesting research topic in recent years. Emotional expressions are rooted in many psychological and physiological factors; therefore, reliable and accurate detection of emotions through facial expressions is not an easy task.

Therefore, the aim of this Special Issue is to present and publish the latest developments in emotion detection based on facial recognition algorithms and related experiments. Researchers in both communities are invited to share their original, unpublished works through this Special Issues.

Topics of interest include, but are not limited to:

  • Emotion detection algorithm design and evaluation;
  • Case studies of emotional detection;
  • Emotional detection experiments based on the commercial products;
  • Applications’ concept of emotion detection through facial recognitions;
  • Security and privacy concern in emotional detection;
  • Social media and emotional detection based on facial recognition.

The human mood has a temporary effect on the face shape due to the movement of its muscles. Happiness, sadness, fear, anger, and other emotional conditions may affect the face biometric system’s reliability. Most of the current studies on facial expressions are concerned about the accuracy of classifying the subjects based on their expressions. This study investigated the effect of facial expressions on the reliability of a face biometric system to find out which facial expression puts the biometric system at greater risk. Moreover, it identified a set of facial features that have the lowest facial deformation caused by facial expressions to be generalized during the recognition process, regardless of which facial expression is presented. In order to achieve the goal of this study, an analysis of 22 facial features between the normal face and six universal facial expressions is obtained. The results show that the face biometric systems are affected by facial expressions where the disgust expression achieved the most dissimilar score, while the sad expression achieved the lowest dissimilar score. Additionally, the study identified the five and top ten facial features that have the lowest facial deformations on the face shape in all facial expressions. Besides that, the relativity score showed less variances between the sample using the top facial features. The obtained results of this study minimized the false rejection rate in the face biometric system and subsequently the ability to raise the system’s acceptance threshold to maximize the intrusion detection rate without affecting the user convenience.
