A multi-scale dual-stream fusion network for high-accuracy SEMG-based gesture classification
The research introduces MSDS-FusionNet, a novel deep learning framework that integrates multi-scale temporal and frequency-domain features for sEMG-based gesture classification. It achieves state-of-the-art accuracy on the NinaPro dataset, with improvements of up to 2.41% (DB2), 2.46% (DB3), and 1.38% (DB4) compared to existing methods. The framework utilizes Multi-Scale Mamba (MSM) modules for multi-scale temporal feature extraction and a Bi-directional Attention Fusion Module (BAFM) for effective feature fusion. This robust solution has significant potential for applications in prosthetics, virtual reality, and assistive technologies, providing high-accuracy recognition of complex gestures.
