Summary: With the advancement of sensor technology and artificial intelligence, video gesture recognition technology using big data has made human-computer interaction more natural and flexible, providing enhanced interactive experiences in teaching, on-board control, electronic gaming, and more. A robust recognition algorithm based on multi-level feature fusion of a two-stream convolutional neural network is proposed to handle challenges like lighting changes, background clutter, rapid movement, and partial occlusion. Experimental results demonstrate that the proposed model can accurately track and recognize gestures, outperforming the single-channel model with improved detection accuracy and mean average precision (mAP). Furthermore, it achieves high recognition rates under occlusion and varying light intensities, showing satisfactory performance compared to other methods in various datasets.
