Current human motion pose recognition using video frames faces challenges in reliably identifying posture segments. While Conv2D excels in spatial feature extraction for image tasks, Conv3D extends into the temporal dimension, making it suitable for video analysis, particularly in action recognition. However, Conv3D's success hinges on the architectural context. Though effective for spatial trends and object recognition, both Conv2D and Conv3D struggle to fully incorporate temporal dynamics inherent in human actions. Conv3D demands substantial labelled data and high computational resources for optimal training, posing challenges in cost and accessibility. This study proposes an alternative: recurrent neural network models (RNNs) with LSTM and GRU layers. These RNNs prove promising for modeling sequential data and capturing temporal nuances in video frames, offering a competitive edge in action detection systems, especially when dealing with intricate temporal dynamics. So the latest research in human action recognition using recurrent neural networks emphasizes the integration of attention mechanisms and spatiotemporal modeling to enhance the model's ability to capture complex temporal dependencies and focus on relevant video frames, resulting in improved recognition accuracy.
