WiFi DensePose

See through walls with WiFi. No cameras. No wearables. Just radio waves.

WiFi DensePose turns commodity WiFi signals into real-time human pose estimation, vital sign monitoring, and presence detection — all without a single pixel of video. By analyzing Channel State Information (CSI) disturbances caused by human movement, the system reconstructs body position, breathing rate, and heartbeat using physics-based signal processing and machine learning.

What	How	Speed
Pose estimation	CSI subcarrier amplitude/phase → DensePose UV maps	54K fps (Rust)
Breathing detection	Bandpass 0.1-0.5 Hz → FFT peak	6-30 BPM
Heart rate	Bandpass 0.8-2.0 Hz → FFT peak	40-120 BPM
Presence sensing	RSSI variance + motion band power	< 1ms latency
Through-wall	Fresnel zone geometry + multipath modeling	Up to 5m depth

# 30 seconds to live sensing — no toolchain required
docker pull ruvnet/wifi-densepose:latest
docker run -p 3000:3000 ruvnet/wifi-densepose:latest
# Open http://localhost:3000

Hardware options for live CSI capture:

Option	Hardware	Cost	Capabilities
ESP32 Mesh (recommended)	3-6x ESP32-S3 + WiFi router	~$54	Presence, motion, breathing, heartbeat
Research NIC	Intel 5300 / Atheros AR9580	~$50-100	Full CSI with 3x3 MIMO
Any WiFi	Windows/Linux laptop	$0	RSSI-based presence and motion

📡 Signal Processing & Sensing — From raw WiFi frames to vital signs

The signal processing stack transforms raw WiFi Channel State Information into actionable human sensing data. Starting from 56-192 subcarrier complex values captured at 20 Hz, the pipeline applies research-grade algorithms (SpotFi phase correction, Hampel outlier rejection, Fresnel zone modeling) to extract breathing rate, heart rate, motion level, and multi-person body pose — all in pure Rust with zero external ML dependencies.

🧠 Models & Training — DensePose pipeline, RVF containers, SONA adaptation

The neural pipeline uses a graph transformer with cross-attention to map CSI feature matrices to 17 COCO body keypoints and DensePose UV coordinates. Models are packaged as single-file .rvf containers with progressive loading (Layer A instant, Layer B warm, Layer C full). SONA (Self-Optimizing Neural Architecture) enables continuous on-device adaptation via micro-LoRA + EWC++ without catastrophic forgetting.

📊 Performance & Benchmarks — Measured throughput, latency, resource usage

All benchmarks are measured on the Rust sensing server using cargo bench and the built-in --benchmark CLI flag. The Rust v2 implementation delivers 810x end-to-end speedup over the Python v1 baseline, with motion detection reaching 5,400x improvement. The vital sign detector processes 11,665 frames/second in a single-threaded benchmark.

Release history

v2.3.0 — 2026-03-01

The largest release to date — delivers the complete end-to-end training pipeline, Docker images, and vital sign detection. The Rust sensing server now supports full model training, RVF export, and progressive model loading from a single binary.

• Docker images published — ruvnet/wifi-densepose:latest (132 MB Rust) and :python (569 MB)
• 8-phase DensePose training pipeline (ADR-023) — Dataset loaders (MM-Fi, Wi-Pose), graph transformer with cross-attention, 6-term composite loss, cosine-scheduled SGD, PCK/OKS validation, SONA adaptation, sparse inference engine, RVF model packaging
• --export-rvf CLI flag — Standalone RVF model container generation with vital config, training proof, and SONA profiles
• --train CLI flag — Full training mode with best-epoch snapshotting and checkpoint saving
• Vital sign detection (ADR-021) — FFT-based breathing (6-30 BPM) and heartbeat (40-120 BPM) extraction, 11,665 fps benchmark
• WiFi scan domain layer (ADR-022) — 8-stage pure-Rust signal intelligence pipeline for Windows WiFi RSSI
• New crates — wifi-densepose-vitals (1,863 lines) and wifi-densepose-wifiscan (4,829 lines)
• 542+ Rust tests — All passing, zero mocks

v2.2.0 — 2026-02-28

Introduced the guided installer, SOTA signal processing algorithms, and the WiFi-Mat disaster response module. This release established the ESP32 hardware path and security hardening.

• Guided installer — ./install.sh with 7-step hardware detection and 8 install profiles
• 6 SOTA signal algorithms (ADR-014) — SpotFi conjugate multiplication, Hampel filter, Fresnel zone model, CSI spectrogram, subcarrier selection, body velocity profile
• WiFi-Mat disaster response — START triage, scan zones, 3D localization, priority alerts — 139 tests
• ESP32 CSI hardware parser — Binary frame parsing with I/Q extraction — 28 tests
• Security hardening — 10 vulnerabilities fixed (CVE remediation, input validation, path security)

v2.1.0 — 2026-02-28

The foundational Rust release — ported the Python v1 pipeline to Rust with 810x speedup, integrated the RuVector signal intelligence crates, and added the Three.js real-time visualization.

• RuVector integration — 11 vendored crates (ADR-002 through ADR-013) for HNSW indexing, attention, GNN, temporal compression, min-cut, solver
• ESP32 CSI sensor mesh — $54 starter kit with 3-6 ESP32-S3 nodes streaming at 20 Hz
• Three.js visualization — 3D body model with 17 joints, real-time WebSocket streaming
• CI verification pipeline — Determinism checks and unseeded random scan across all signal operations
