Episode 13: MultiFormer: A Multi-Person Pose Estimation System Based on CSI and Attention Mechanism

In this short technical breakdown, I review the MultiFormer paper — a cutting-edge, vision-free human pose estimation framework that leverages WiFi Channel State Information (CSI) and Transformer-based neural networks. MultiFormer introduces a Time-Frequency Dual-Dimensional Tokenization (TFDDT) scheme to extract meaningful temporal and spectral features from raw CSI, feeding them into a dual-branch Transformer architecture with multi-head self-attention. The system then refines pose predictions using a Multi-Stage Feature Fusion Network (MSFN) and attention-guided heatmap decoding. Key highlights: Outperforms existing wifi-based systems especially in multi-person scenarios Accurately estimates high-mobility joints like wrists and elbows Achieves state-of-the-art results on both MM-Fi and custom datasets 🔍 Paper Link: https://arxiv.org/abs/2505.22555 📡 Research Field: CSI-based Human Pose Estimation 📡 Check out my courses here: https://www.drnirregev.com/courses #WiFiSensing #AI #Transformers #HumanPoseEstimation #CSI #DeepLearning #PaperReview #MultiFormer #RadarAI #NirRegevExplains
