Classification: CPC G | IPC G

Claim 22:
23. The device of claim 21, wherein to perform the AI-based method for extracting body key points for calculating physical function features for the POI, the at least one processor is configured to:
receive a video frame containing the POI;
crop the video frame to generate a cropped image;
feed the cropped image into an artificial neural network to produce a heatmap tensor and an offset tensor;
determine output dimensions based at least in part on a size of the cropped image;
process the heatmap tensor and the offset tensor based at least in part on the output dimensions to estimate poses of the POI and generate respective confidence values; and
produce a final output of body key point coordinates based on the estimated poses and the respective confidence values.
