Filters & Processing

Filtering and signal processing tools for mass mapping.

This module provides various filtering techniques including aperture mass filters, starlet wavelet transforms, and smoothing operations.

Aperture Mass Filters

smpy.filters.processing.schirmer_filter	Compute Schirmer filter values for given scaled radii.
smpy.filters.processing.schneider_filter	Compute Schneider filter values for given scaled radii.
smpy.filters.processing.create_filter_kernel	Create a 2D kernel for any aperture mass filter.
smpy.filters.processing.apply_filter_convolution	Apply a filter kernel via convolution.
smpy.filters.processing.apply_aperture_filter	Apply aperture filter based on configuration.

Starlet Wavelet Processing

smpy.filters.starlet.b3spline_filter	Create a B3-spline filter for the starlet transform.
smpy.filters.starlet.apply_filter	Apply separable convolution with the given kernel.
smpy.filters.starlet.starlet_transform_2d	Compute the isotropic undecimated wavelet transform of an image.
smpy.filters.starlet.inverse_starlet_transform_2d	Reconstruct an image from its starlet transform coefficients.

Plotting Filters

smpy.filters.plotting.apply_filter

Apply filtering to input data.
