topapprox
Authors: Matias de Jong van Lier, Junyan Chu, Sebastían Elías Graiff Zurita, Shizuo Kaji
topapprox is a Python package for persistent-homology-based filtering of scalar signals on:
- 1D, 2D, and 3D arrays
- graphs with faces
Low-persistence filtering removes topological features that are small relative to a chosen threshold epsilon.
In practice:
- Build the persistence diagram of the input signal.
- Identify features whose persistence is smaller than
epsilon. - Modify the signal so those low-persistence features disappear, while the more significant ones remain.
This makes the filter useful for denoising and simplification: small oscillations, shallow basins, and weak cycles are removed, while large-scale structure is preserved. For array signals, the filtered output remains within epsilon in the L^inf norm of the original input.
Installation
From PyPI:
pip install topapprox
From source:
python -m pip install -e ".[dev]"
Quick Start
import numpy as np
import topapprox as ta
from topapprox.persistence import get_PD_gwf
img = np.array([[0, 5, 3], [5, 6, 4], [2, 5, 1]], dtype=float)
image_filter = ta.ImageFilter(img, method="python")
filtered_h0 = image_filter.low_pers_filter(1.5)
dual_filter = ta.ImageFilter(img, dual=True, method="python")
filtered_h1 = dual_filter.low_pers_filter(1.5)
faces = [[0, 1, 2, 3]]
holes = [[0, 1, 2, 3]]
signal = np.array([0.0, 1.0, 0.5, 0.2])
graph_filter = ta.GraphFilter(method="python")
graph_filter.compute_gwf(F=faces, H=holes, signal=signal)
pd0, pd1 = graph_filter.get_diagram()
persistence_filter = ta.PersistenceFilter().load_signal(img)
filtered_01 = persistence_filter.low_pers_filter(1.5, iteration_order="01", method="python")
pd0_fn, pd1_fn = get_PD_gwf(faces, holes, signal, method="python")

Development
Run the full test suite:
python -m pytest -q
Build distributions locally:
python -m build --wheel --sdist
Binary wheels are built with cibuildwheel, and the native extension is compiled through scikit-build-core + CMake.
