source module nabu.preproc.double_flatfield_cuda

Classes

• CudaDoubleFlatField — Init double flat field with Cuda backend.

source class CudaDoubleFlatField(shape, result_url=None, sub_region=None, detector_corrector=None, input_is_mlog=True, output_is_mlog=False, average_is_on_log=False, sigma_filter=None, filter_mode='reflect', log_clip_min=None, log_clip_max=None, cuda_options=None)

Bases : DoubleFlatField

Init double flat field with Cuda backend.

Methods

• compute_double_flatfield — Read the radios and generate the "double flat field" by averaging and possibly other processing.

• get_double_flatfield — Get the double flat field or a subregion of it.

• apply_double_flatfield — Apply the "double flatfield" filter on a chunk of radios. The processing is done in-place !

source method CudaDoubleFlatField.compute_double_flatfield(radios, recompute=False)

Read the radios and generate the "double flat field" by averaging and possibly other processing.

Parameters

• radios : array — Input radios chunk.

• recompute : bool, optional — Whether to recompute the double flatfield if already computed.

Raises

• TypeError

source method CudaDoubleFlatField.get_double_flatfield(radios=None, compute=False)

Get the double flat field or a subregion of it.

Parameters

• radios : array, optional — Input radios chunk

• compute : bool, optional — Whether to compute the double flatfield anyway even if a dump file exists.

Raises

• ValueError

source method CudaDoubleFlatField.apply_double_flatfield(radios)

Apply the "double flatfield" filter on a chunk of radios. The processing is done in-place !
