patch_denoise.simulation.noise.add_temporal_rician_noise

patch_denoise.simulation.noise.add_temporal_rician_noise(array, scale=1, rng=None)

Add center rician noise to array.

Parameters:

• array (numpy.ndarray) – The noise-free array

• sigma (float) – The scale of the Rice distribution

Notes

This function considered centered Rician noise [1], and thus the noise generated follows a Rayleigh distribution [2].
