class brainrise.intensity.RandomGhosting(axis, n_ghosts=10, intensity=1, seed=None)[source]¶

Add random MRI ghosting artifact.

Leave first 5% of frequencies untouched.

__init__(axis, n_ghosts=10, intensity=1, seed=None)[source]¶

Init class.

Parameters

axis : int

the axis along which the ghosts artifact will be created.

n_ghosts : int or 2-uplet, default 10

the number of ghosts in the image. Larger values generate more distorted images.

intensity : float or list of float, default 1

a number between 0 and 1 representing the artifact strength. Larger values generate more distorted images.

seed : int, default None

seed to control random number generator.
