Self-Difference Convolutional Neural Network for Facial Expression Recognition

Sensors, 2021
Facial expression recognition (FER) is a challenging problem due to the intra-class variation caused by subject identities. In this paper, a self-difference convolutional network (SD-CNN) is proposed to address the intra-class variation issue in FER ...

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.

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)

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.

Training deep networks for facial expression recognition with crowd-sourced label distribution [PDF]

International Conference on Multimodal Interaction, 2016
Crowd sourcing has become a widely adopted scheme to collect ground truth labels. However, it is a well-known problem that these labels can be very noisy.

The language context effect in facial expressions processing and its mandatory characteristic

Scientific Reports, 2019
Background visual scenes in which faces are perceived provide contextual information for facial expression processing. One type of background information, the language context, has a vital influence on facial expression processing.

A Comparison of the Affectiva iMotions Facial Expression Analysis Software With EMG for Identifying Facial Expressions of Emotion

Frontiers in Psychology, 2020
Human faces express emotions, informing others about their affective states. In order to measure expressions of emotion, facial Electromyography (EMG) has widely been used, requiring electrodes and technical equipment.
