class mantidimaging.core.operations.remove_all_stripe.remove_all_stripe.RemoveAllStripesFilter

Bases: BaseFilter

Stripe and ring artifact removal. Remove all types of stripe artifacts by combining algorithm 6, 5, and 3 in Vo et al., Optics Express 28396 (2018).

Source: https://github.com/algotom/algotom

Intended to be used on: Sinograms

When: If stripes artifacts are present that have not been removed with outliers + flat-fielding the projections

Caution: Horizontal stripes caused by changes in image intensity (pixel values) should be fixed by ROI Normalisation instead!

static execute_wrapper(snr: QDoubleSpinBox, la_size: QSpinBox, sm_size: QSpinBox, dim: QSpinBox)

Should construct a partial call to _filter_func using values taken from the widgets passed to this function as kwargs. :param kwargs: widgets which contain values required for _filter_func. :return: a partial call to _filter_func using parameters taken from the input widgets.

static filter_func(images: Images, snr=3, la_size=61, sm_size=21, dim=1, cores=None, chunksize=None, progress=None)

Executes the filter algorithm on a given set of image data with the given parameters.

Parameters:

• data – the image data to apply the filter to

• kwargs – any additional arguments which the specific filter uses

Returns:

the image data after applying the filter

filter_name = 'Remove all stripes'

static group_name() → FilterGroup

link_histograms = True

static register_gui(form, on_change, view)

Adds any required input widgets to the given form and returns references to them.

The return values should be in a dict which can be unpacked as kwargs for a call to the operations execute_wrapper.

Parameters:

• view –

• form – the layout to create input widgets in

• on_change – the filter view action to be bound to all created inputs

Returns:

the widgets bound as kwargs which are needed to call execute_wrapper
