Crate wifi_densepose_signal 

WiFi-DensePose Signal Processing Library

This crate provides signal processing capabilities for WiFi-based human pose estimation, including CSI (Channel State Information) processing, phase sanitization, feature extraction, and motion detection.

Features

• CSI Processing: Preprocessing, noise removal, windowing, and normalization
• Phase Sanitization: Phase unwrapping, outlier removal, and smoothing
• Feature Extraction: Amplitude, phase, correlation, Doppler, and PSD features
• Motion Detection: Human presence detection with confidence scoring

Example

use wifi_densepose_signal::{
    CsiProcessor, CsiProcessorConfig,
    PhaseSanitizer, PhaseSanitizerConfig,
    MotionDetector,
};

// Configure CSI processor
let config = CsiProcessorConfig::builder()
    .sampling_rate(1000.0)
    .window_size(256)
    .overlap(0.5)
    .noise_threshold(-30.0)
    .build();

let processor = CsiProcessor::new(config);
