Facial Expression Manipulation for Personalized Facial Action Estimation

Frontiers in Signal Processing, 2022
Limited sizes of annotated video databases of spontaneous facial expression, imbalanced action unit labels, and domain shift are three main obstacles in training models to detect facial actions and estimate their intensity.

Investigating facial animation production through artistic inquiry [PDF]

, 2009
Studies into dynamic facial expressions tend to make use of experimental methods based on objectively manipulated stimuli. New techniques for displaying increasingly realistic facial movement and methods of measuring observer responses are typical of ...

Research on facial expression recognition based on an improved fusion algorithm

Nonlinear Engineering, 2022
This article puts forward a facial expression recognition (FER) algorithm based on multi-feature fusion and convolutional neural network (CNN) to solve the problem that FER is susceptible to interference factors such as non-uniform illumination, thereby ...

EMPATH: A Neural Network that Categorizes Facial Expressions [PDF]

, 2002
There are two competing theories of facial expression recognition. Some researchers have suggested that it is an example of "categorical perception." In this view, expression categories are considered to be discrete entities with sharp boundaries, and ...

Geometric Feature-Based Facial Expression Recognition in Image Sequences Using Multi-Class AdaBoost and Support Vector Machines

Sensors, 2013
Facial expressions are widely used in the behavioral interpretation of emotions, cognitive science, and social interactions. In this paper, we present a novel method for fully automatic facial expression recognition in facial image sequences.

Adaptive 3D Model-Based Facial Expression Synthesis and Pose Frontalization

Sensors, 2020
Facial expressions are one of the important non-verbal ways used to understand human emotions during communication. Thus, acquiring and reproducing facial expressions is helpful in analyzing human emotional states.

Does gaze direction modulate facial expression processing in children with autism spectrum disorder? [PDF]

, 2009
Two experiments investigated whether children with autism spectrum disorder (ASD) integrate relevant communicative signals, such as gaze direction, when decoding a facial expression. In Experiment 1, typically developing children (9–14 years old; n = 14)

A practice-led approach to facial animation research [PDF]

, 2010
In facial expression research, it is well established that certain emotional expressions are universally recognized. Studies into the observer perception of dynamic expressions have built upon this research by highlighting the importance of particular ...

Expression Conditional GAN for Facial Expression-to-Expression Translation

, 2019
In this paper, we focus on the facial expression translation task and propose a novel Expression Conditional GAN (ECGAN) which can learn the mapping from one image domain to another one based on an additional expression attribute. The proposed ECGAN is a
