Contrast to Noise Ratio (CNR)ΒΆ
Module for calculating the contrast-to-noise ratio (CNR) for an image.
Examples
>>> import numpy as np
>>> from viqa import CNR
>>> img = np.random.rand(256, 256)
>>> cnr = CNR(data_range=1, normalize=False)
>>> cnr
CNR(score_val=None)
>>> score = cnr.score(img,
... background_center=(128, 128),
... signal_center=(32, 32),
... radius=16)
