iPhone Screenshots


This iOS app provides an interface for taking photos of people raising their hands, uploading them to a server running an HRNet pose estimation network, and visualizing the predicted head and hand locations. Uploaded images are also saved to help create a more representative dataset for further training. It works surprisingly well given no task-specific training, but is very much a proof of concept and should not be relied upon where accuracy is important.
