ewoksndreg.evaluation.eval_metrics.noisy_eval(stack)

Determines how noisy the images in the given stack are.

This is determined by denoising the image with a gaussian filter and comparing the variance before and after. Return value is big if the denoising decreased the variance a lot.

Parameters:

stack (ndarray) – array of shape [N,H,W]

Return type:

float
