Swinging Door Algorithm

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}")
