wifi-densepose/v2/crates

WiFi-DensePose Rust Crates

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

A modular Rust workspace for WiFi-based human pose estimation, vital sign monitoring, and disaster response using Channel State Information (CSI). Built on RuVector graph algorithms and the WiFi-DensePose research platform by rUv.

Quick Start

As a Library

use wifi_densepose_core::{CsiFrame, CsiMetadata, SignalProcessor};
use wifi_densepose_signal::{CsiProcessor, CsiProcessorConfig};

// Configure the CSI processor
let config = CsiProcessorConfig::default();
let processor = CsiProcessor::new(config);

// Process a CSI frame
let frame = CsiFrame { /* ... */ };
let processed = processor.process(&frame)?;

Vital Sign Monitoring

use wifi_densepose_vitals::{
    CsiVitalPreprocessor, BreathingExtractor, HeartRateExtractor,
    VitalAnomalyDetector,
};

let mut preprocessor = CsiVitalPreprocessor::new(56); // 56 subcarriers
let mut breathing = BreathingExtractor::new(100.0);    // 100 Hz sample rate
let mut heartrate = HeartRateExtractor::new(100.0);

// Feed CSI frames and extract vitals
for frame in csi_stream {
    let residuals = preprocessor.update(&frame.amplitudes);
    if let Some(bpm) = breathing.push_residuals(&residuals) {
        println!("Breathing: {:.1} BPM", bpm);
    }
}

Disaster Response (MAT)

use wifi_densepose_mat::{DisasterResponse, DisasterConfig, DisasterType};

let config = DisasterConfig {
    disaster_type: DisasterType::Earthquake,
    max_scan_zones: 16,
    ..Default::default()
};

let mut responder = DisasterResponse::new(config);
responder.add_scan_zone(zone)?;
responder.start_continuous_scan().await?;

Hardware (ESP32)

use wifi_densepose_hardware::{Esp32CsiParser, CsiFrame};

let parser = Esp32CsiParser::new();
let raw_bytes: &[u8] = /* UDP packet from ESP32 */;
let frame: CsiFrame = parser.parse(raw_bytes)?;
println!("RSSI: {} dBm, {} subcarriers", frame.metadata.rssi, frame.subcarriers.len());
