Preprocessor

Constructor

Preprocessor

Implements filtering operations on density arrays.

Filters

Preprocessor.continuous_wedge_mask(...[, ...])	Generate a wedge in a given shape based on specified tilt angles and axis.
Preprocessor.step_wedge_mask(shape[, ...])	Create a wedge mask with the same shape as template by rotating a plane according to tilt angles.
Preprocessor.gaussian_filter(template, sigma)	Convolve an atomic structure with a Gaussian kernel.
Preprocessor.difference_of_gaussian_filter(...)	Apply the Difference of Gaussian (DoG) bandpass filter on the provided template.
Preprocessor.bandpass_filter(template, ...)	Apply a band-pass filter on the provided template, using a Butterworth approximation.
Preprocessor.local_gaussian_alignment_filter(...)	Simulate electron density by optimizing a sum of Gaussians.
Preprocessor.local_gaussian_filter(template, ...)	Wrapper for Preprocessor.local_gaussian_alignment_filter if no target is available.
Preprocessor.edge_gaussian_filter(template, ...)	Perform Gaussian filterring according to edges in the input template.
Preprocessor.mean_filter(template, width)	Perform mean filtering.
Preprocessor.rank_filter(template, rank)	Perform rank filtering.
Preprocessor.mipmap_filter(template, level)	Perform mip map antialiasing filtering.
Preprocessor.kaiserb_filter(template, width)	Apply Kaiser filter defined as:
Preprocessor.blob_filter(template, width)	Apply blob filter defined as:
Preprocessor.hamming_filter(template, width)	Apply Hamming filter defined as:

Utilities

Preprocessor.interpolate_box(arr, box[, kind])

Resample arr within box using kind interpolation.
