    摘要: Provided herein are methods and systems for recognizing an infant action in a recorded video. The infant action recognition technique includes performing pose estimation for each frame of the video, where pose corresponds to skeletal joint locations and joint angles. A posture classifier uses the pose estimations to classify each pose estimation as one of five postures and a probability value for the posture. The infant action recognition technique further includes using the identified postures for each frame and the probability values to determine a period of uncertainty that corresponds to a transition segment. The infant action recognition technique further includes using the first and last frames of the transition segment to distinguish start and end stable postures. The technique further includes performing filtering and majority voting to remove outlier posture classifications and determine an infant action label for the video based on the start and end stable postures.
