Swinging Door Algorithm real time compression

This module is the implementation of the swinging door algorithm in Python.

Install

pip install swingingpy

Usage

    from swingingpy import SwingingDoor, Cpoint

    comp_dev = 1
    comp_max = 5
    original = CPoint(0, 0)
    snapshot = None

    sd = SwingingDoor(
        comp_dev=comp_dev, 
        comp_max=comp_max, 
        original=original, 
        snapshot=snapshot
    )

    points = [
        CPoint(1, 0),
        CPoint(2, 5),
        CPoint(3, 6),
    ]

    for p in points:
        point = compressor.check(p)

        if point:
            print(f"Compressed {point}")
        else:
            print(f"Uncompressed {point}")
