Construct a new ICUUnwrap object.

Parameters

min_coherencefloat, optional

Minimum coherence of valid data. Pixels with lower coherence are masked out. Defaults to 0.1.

ntreesint, optional

Number of randomized tree realizations to generate. Defaults to 7.

max_branch_lengthint, optional

Maximum length of a branch cut between residues/neutrons, in pixels. Defaults to 64.

use_phasegrad_neutronsbool, optional

Whether to use phase gradient neutrons. Defaults to False.

use_intensity_neutronsbool, optional

Whether to use intensity neutrons. Defaults to False.

phasegrad_window_sizeint, optional

Window size for estimating phase gradients. This parameter is ignored if use_phasegrad_neutrons was false. Defaults to 5.

neutron_phasegrad_threshfloat, optional

Absolute phase gradient threshold for detecting phase gradient neutrons, in radians per sample. This parameter is ignored if use_phasegrad_neutrons was false. Defaults to 3.

neutron_intensity_threshfloat, optional

Intensity variation threshold for detecting intensity neutrons, in standard deviations from the mean (based on local image statistics). This parameter is ignored if use_intensity_neutrons was false. Defaults to 8.

neutron_coherence_threshfloat, optional

Sample coherence threshold for detecting intensity neutrons. This parameter is ignored if use_intensity_neutrons was false. Defaults to 0.8.

min_conncomp_area_fracfloat, optional

Minimum connected component size as a fraction of the total size of the interferogram tile. Defaults to 1/320.
