Abstract (en)
[origin: WO2022208168A1] Systems and methods described herein enable automated motion recognition by receiving a time-series of images depicting a subject at a plurality of time points. For each image in the time-series of images, an orientation key-point associated with a section of a body part of the subject are predicted via a neural network detector, a three-axis joint rotation associated with the section of the body part is computed based on the orientation key-point associated with the body part and a joint key -point associated with the body part, and features are generated including at least one of: the orientation key-point, the joint key-point, or the three-axis joint rotation. A motion performed by the subject is predicted via a motion recognition machine learning model based on the features of each image in the time-series of images, and an operation is executed in response to the motion.
