Brief Summary

The aim of this project is to successfully develop and industrialise the "Facial Movement 3D Dynamic Quantitative Measurement Device", which is a commercial device that can provide dynamic indicators of facial movement, and can practically solve the evaluation problems of facial paralysis for doctors and patients, and has important clinical value and social benefits.

Conditions

Facial Palsy

Outcome Measures

Primary Outcomes (2)

• Facial feature point displacement distance

  Displacement of corresponding facial feature points when volunteers perform specific actions such as specific expressions (raising eyebrow, closing eyes, shrugging nose, smiling and whistling)

  3 months

• Facial Feature Point Velocity

  Velocity of the corresponding facial feature points of volunteers when accomplishing specific actions such as specific expressions (raising eyebrows, closing eyes, shrugging nose, smiling, whistling)

  3 months

Study Arms (2)

training session

A total of 150 facial expression videos of healthy volunteers and facial palsy patients were collected as a training set for the algorithm

Other: non-intervention

test set

A total of 50 cases of healthy volunteers and patients with facial palsy were used as the test set for the algorithm

Other: non-intervention

Interventions

non-intervention OTHER

non-intervention

test set; training session

Eligibility Criteria

• Age: 14 Years - 70 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Based on previous face data collection often use larger public datasets, such as the AFLW dataset with 20,000 images. we need the same order of magnitude of local ethnographic data for migration learning. At the same time, the data in the dataset is improved according to the need to improve the accuracy of the labelled data at key points. Take about 100 effective frames for each data set. Need to complete about 200 people of various types of face data acquisition. The test group data is generally designed to be more than 20% of the training data, so the number of test group samples is designed to be 50 groups.

You may qualify if:

• Older than 14 years
• No history of facial surgery, facial trauma, or scars obscuring the facial features.
• Able to perform relevant actions according to instructions
• Willingness to participate in the study

You may not qualify if:

• Unwillingness to participate in the study
• Unable to co-operate with relevant command actions
• Obvious trauma, scars, etc. obscuring the facial features
• Less than 14 years of age
