Ring Removal Waveletfft

Description

Wavelet-FFt-based method working in the sinogram space to remove ring artifacts.

• Plugin documention and guidelines on use

Parameters

in_datasets:
    visibility: datasets
    dtype: "[list[],list[str]]"
    description:
        summary: A list of the dataset(s) to process.
        verbose: A list of strings, where each string gives the name of a dataset that was either specified by a loader plugin or created as output to a previous plugin.  The length of the list is the number of input datasets requested by the plugin.  If there is only one dataset and the list is left empty it will default to that dataset.
    default: "[]"

out_datasets:
    visibility: datasets
    dtype: "[list[],list[str]]"
    description:
        summary: A list of the dataset(s) to create.
        verbose: A list of strings, where each string is a name to be assigned to a dataset output by the plugin. If there is only one input dataset and one output dataset and the list is left empty, the output will take the name of the input dataset. The length of the list is the number of output datasets created by the plugin.
    default: "[]"

sigma:
    visibility: basic
    dtype: int
    description: Damping parameter. Larger is stronger.
    default: "1"

level:
    visibility: basic
    dtype: int
    description: Wavelet decomposition level.
    default: "4"

nvalue:
    visibility: intermediate
    dtype: int
    description: Order of the the Daubechies (DB) wavelets.
    default: "8"

padFT:
    visibility: intermediate
    dtype: int
    description: Padding for Fourier transform
    default: "20"

Key

visibility: The visibility level of the parameter
dtype: The type of data
description: A short explanation of the parameter
default: The default value
options: A list of permitted values
dependency: The name of the parameter and value which this parameter depends upon
range: A guide for the range of the parameter

API

class RingRemovalWaveletfft

get_max_frames()

get_plugin_pattern()

pre_process()

This method is called immediately after base_pre_process().

process_frames(data)

This method is called after the plugin has been created by the pipeline framework and forms the main processing step

Parameters

data (list(np.array)) – A list of numpy arrays for each input dataset.
