Automatic Facial Expression Analysis

Facial expression analysis is an active area in human-computer interaction. Many techniques of facial expression analysis have been proposed that try to make the interaction tighter and more efficient. The essence of facial expression analysis is to recognize facial actions or to perceive human emotion through the changes of the face surface. Generally, there are three main steps in analyzing f...

Automatic facial expression analysis

Humans spend a large amount of their time interacting with computers of one type or another. However, computers are emotionally blind and indifferent to the affective states of their users. Human-computer interaction which does not consider emotions, ignores a whole channel of available information. Faces contain a large portion of our emotionally expressive behaviour.

Automatic Analysis of Facial Actions: A Survey

As one of the most comprehensive and objective ways to describe facial expressions, the Facial Action Coding System (FACS) has recently received significant attention. Over the past 30 years, extensive research has been conducted by psychologists and neuroscientists on various aspects of facial expression analysis using FACS. Automating FACS coding would make this research faster and more widel...

Facial expression analysis and synthesis: A survey

Human facial expression analysis and synthesis play a central role in the social context, being investigated by many psychologists over the time. Moreover, an increased interest has been shown in developing an automated facial expression analyzer capable of recognizing, classifying and then synthesizing human expressions on synthetic “talking heads”. This paper surveys the state of the art in t...
