Package Exports

bioleptic-js
bioleptic-js/bioleptic_js.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bioleptic-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Bioleptic

Wavelet-based signal compression for physiological data (ECG, PPG, accelerometry).

Algorithm

Non-finite substitution (NaN → 0, ±inf → 0/1)
Mean-centering + range normalization
Multi-level DWT (CDF 5/3 or CDF 9/7, 5 levels)
Quantization to i16 with configurable scale
Detail coefficient thresholding
Entropy coding with deflate

Rust

let compressed = compress(&signal, CompressionOptions::default())?;
let recovered  = decompress(&compressed)?;

Python

pip install bioleptic

from bioleptic import compress_signal, decompress_signal, BiolpCompressionOptions

compressed = compress_signal(signal, BiolpCompressionOptions("cdf97", 11, "low"))
recovered  = decompress_signal(compressed)

JavaScript

npm install bioleptic

import init, {compress_signal, decompress_signal} from "bioleptic";

await init();

const signal = new Float32Array([...]);

const options = new BiolpCompressionOptions(
    BiolpCompressionMethod.Cdf97,
    BiolpQuantizationScale.S11,
    BiolpCutoffLevel.Medium,
);

const compressed = compress_signal(signal, options);  // Uint8Array
const recovered  = decompress_signal(compressed);     // Float32Array
