WebJul 26, 2024 · To classify an action, we first need locate various body parts in every frame, and then analyze the movement of the body parts over time. The first step is achieved using Detectron2 which outputs the body posture (17 key points) after observing a single frame in a video. The second step of analyzing the motion of the body over time and making a ... WebSep 27, 2024 · We will create and train a neural network with Linear layers and we will employ a Softmax activation function and the Adam optimizer.
