cwitools.imaging.slice_fix

cwitools.imaging.slice_fix(image, mask=None, axis=0, scval=3)

Perform slice-by-slice median correction in an image.

Args:

image (NumPy.ndarray): The input image data. mask (NumPy.ndarray): A corresponding mask, used to exclude pixels from

the median calculation ((>=1)=ignore, 0=use)

axis (int): The axis along which to subtract. scval (float): The sigma-clipping threshold applied before median calculation.

Returns:

numpy.ndarray: The slice-by-slice median subtracted image.
