Automatic facial expression recognition constitutes an active research field due to the latest
advances in computing technology that make the user's experience a clear priority. The …

In recent years, facial expression analysis and recognition (FER) have emerged as an active
research topic with applications in several different areas, including the human-computer …

This survey focuses on discrete expression classification and facial action unit recognition
performed using 3D face data, possibly including a corresponding 2D texture image …

Facial expression analysis has interested many researchers in the past decade due to its
potential applications in various fields such as human–computer interaction, psychological …

Distance measures and geometrical features are widely used to describe faces. Generally,
they are extracted punctually from landmarks, namely anthropometric reference points. The …

Abstract 3D facial expression recognition has been greatly promoted for overcoming the
inherent drawbacks of 2D facial expression recognition and has achieved superior …

Emotions analysis and recognition by the smartphones with front cameras is a relatively new
concept. In this paper we present an algorithm that uses a low resolution 3D sensor for facial …

We propose a new linear model, based on resampling 3D face meshes to convert them to
3D matrices, to recognize identity and expression simultaneously. This contrasts with …

We present a semi-automatic 3D Facial Expression Recognition system based on geometric
facial information. In this approach, the 3D facial meshes are first fitted to an Annotated Face …

The research on 3D facial expression recognition has attracted numbers of interests due to
its superiority to 2D data and it has been greatly promoted in recent years. However, its …
