Facial Expression Analysis


September 8, 2015
2:00pm-6:00pm
7th IEEE International Conference on Biometrics
BTAS 2015
Arlington, Virginia

 

 


Description

The face is one of the most powerful channels of nonverbal communication. Facial expression provides cues about emotion, intention, alertness, pain, personality, regulates interpersonal behavior, and communicates psychiatric and biomedical status among other functions. Within the past 15 years, there has been increasing interest in automated facial expression analysis within the computer vision and machine learning communities. This tutorial will review fundamental approaches to facial measurement by behavioral scientists and current efforts in automated facial expression recognition. We consider challenges, review databases available to the research community, approaches to feature detection, tracking, and representation, and both supervised and unsupervised learning. In addition, we will discuss applications of facial image analysis to clinical depression, personality processes, pain assessment and the use of facial expression as biometrics.


Program

Introduction

Facial Action Coding System (FACS)

Computational models for Facial Expression Analysis

  • Registration
  • Features
  • Supervised Facial Expression Analysis
  • Unsupervised Facial Expression Analysis

Applications to:

  • Clinical depression
  • Pain Assessment
  • Facial expression as biometrics
  • Personality and facial expression

Conclusions and open problems


Target participants

The tutorial is targeted to researchers or practitioners that use video to analyze facial behavior. The tutorial will be self-contained. Basic knowledge on computer vision will be required to understand some of the methods, but in the second part of the tutorial (application area) no knowledge on computer vision is required.
