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.
Based on the current optimal high-precision face key point technology, the effective high-precision automatic face recognition model conforming to the Asian face is established through specialised training with targeted marker data, time series training optimisation based on optical flow, and local image tracking technology. The 3D reconstruction technique is then used to reconstruct the 3D spatial coordinates of the face keypoints, so as to realise the multi-camera 3D tracking of the face keypoints. The displacement of the key points is used to respond to the facial muscle activity characteristics of facial paralysis patients.
81 studies on the registry are indexed under Facial Paralysis; 28 are open to participants now.
This study's planned enrollment of 200 is above the median of 80 across 21 observational studies indexed under Facial Paralysis.

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.

Time frame: 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)
Time frame: 3 months
