The perception and mimicry of facial movements predict judgments of smile authenticity. [PDF]

PLoS ONE, 2014
The mechanisms through which people perceive different types of smiles and judge their authenticity remain unclear. Here, 19 different types of smiles were created based on the Facial Action Coding System (FACS), using highly controlled, dynamic avatar ...

MMNet: Muscle motion-guided network for micro-expression recognition [PDF]

Proc. 31st Int'l Joint Conf. Artificial Intelligence (IJCAI), 2022, 2022
Facial micro-expressions (MEs) are involuntary facial motions revealing peoples real feelings and play an important role in the early intervention of mental illness, the national security, and many human-computer interaction systems. However, existing micro-expression datasets are limited and usually pose some challenges for training good classifiers ...

3D-Ultrasonography for evaluation of facial muscles in patients with chronic facial palsy or defective healing: a pilot study

BMC Ear, Nose and Throat Disorders, 2014
BackgroundWhile standardized methods are established to examine the pathway from motorcortex to the peripheral nerve in patients with facial palsy, a reliable method to evaluate the facial muscles in patients with long-term palsy for therapy planning is ...

Newly identified axon types of the facial nerve unveil supplemental neural pathways in the innervation of the face

Journal of Advanced Research, 2023
Introduction: Neuromuscular control of the facial expressions is provided exclusively via the facial nerve. Facial muscles are amongst the most finely tuned effectors in the human motor system, which coordinate facial expressions.

SOMATOTOPY OF THE FACIAL NUCLEUS: A COMPARATIVE ANALYSIS WITH CLINICAL REMARKS [PDF]

Euromediterranean Biomedical Journal, 2023
Stemming from our previous studies regarding somatotopy of the spinal cord, oculomotor complex and trigeminal complex, we developed this study of the somatotopy of facial nuclei to compare the musculotopic organization of the facial nucleus in different ...

Automatic Facial Paralysis Estimation with Facial Action Units [PDF]

arXiv, 2022
Facial palsy is unilateral facial nerve weakness or paralysis of rapid onset with unknown causes. Automatically estimating facial palsy severeness can be helpful for the diagnosis and treatment of people suffering from it across the world. In this work, we develop and experiment with a novel model for estimating facial palsy severity.

Emotion Separation and Recognition from a Facial Expression by Generating the Poker Face with Vision Transformers [PDF]

, 2022
Representation learning and feature disentanglement have garnered significant research interest in the field of facial expression recognition (FER). The inherent ambiguity of emotion labels poses challenges for conventional supervised representation learning methods.

The development of spontaneous facial responses to others’ emotions in infancy. An EMG study [PDF]

, 2017
Viewing facial expressions often evokes facial responses in the observer. These spontaneous facial reactions (SFRs) are believed to play an important role for social interactions.

Human Expression Recognition using Facial Shape Based Fourier Descriptors Fusion [PDF]

Proceedings Volume 11433, Twelfth International Conference on Machine Vision (ICMV 2019); 114330P (2020), 2020
Dynamic facial expression recognition has many useful applications in social networks, multimedia content analysis, security systems and others. This challenging process must be done under recurrent problems of image illumination and low resolution which changes at partial occlusions.

Magnetic resonance imaging of facial muscles

Clinical Radiology, 2007
Facial and tongue muscles are commonly involved in patients with neuromuscular disorders. However, these muscles are not as easily accessible for biopsy and pathological examination as limb muscles. We have previously investigated myasthenia gravis patients with MuSK antibodies for facial and tongue muscle atrophy using different magnetic resonance ...
