I came across an example that starts as follows:
from scipy.ndimage import filters
img = zeros(im.shape)
What does the second line mean here? Is it setting the image pixels to
zero? What is "shape" here?
It looks like it might be using numpy.
If 'im' is a numpy array representing an image, then its .shape
attribute is giving its 'shape' (a tuple of the sizes of its
dimensions).
numpy.zeros(...) will when return a numpy array of the same shape.
So, it's not setting the image pixels to 0, but creating a new image of
the same shape in which the pixels are 0.
