Miscellaneous routines (:mod:`scipy.misc`) 

========================================== 

.. currentmodule:: scipy.misc 

Various utilities that don't have another home. 

Note that Pillow (https://python-pillow.org/) is not a dependency 

of SciPy, but the image manipulation functions indicated in the list 

below are not available without it. 

.. autosummary:: 

:toctree: generated/ 

ascent - Get example image for processing 

central_diff_weights - Weights for an n-point central m-th derivative 

derivative - Find the n-th derivative of a function at a point 

face - Get example image for processing 

electrocardiogram - Load an example of a one-dimensional signal. 

Deprecated functions: 

.. autosummary:: 

:toctree: generated/ 

bytescale - Byte scales an array (image) [requires Pillow] 

fromimage - Return a copy of a PIL image as a numpy array [requires Pillow] 

imfilter - Simple filtering of an image [requires Pillow] 

imread - Read an image file from a filename [requires Pillow] 

imresize - Resize an image [requires Pillow] 

imrotate - Rotate an image counter-clockwise [requires Pillow] 

imsave - Save an array to an image file [requires Pillow] 

imshow - Simple showing of an image through an external viewer [requires Pillow] 

toimage - Takes a numpy array and returns a PIL image [requires Pillow] 

Deprecated aliases: 

.. autosummary:: 

:toctree: generated/ 

comb - Combinations of N things taken k at a time, "N choose k" (imported from `scipy.special`) 

factorial - The factorial function, ``n! = special.gamma(n+1)`` 

(imported from `scipy.special`) 

factorial2 - Double factorial, ``(n!)!`` (imported from `scipy.special`) 

factorialk - ``(...((n!)!)!...)!`` where there are k '!' (imported from `scipy.special`) 

logsumexp - Compute the log of the sum of exponentials of input elements 

(imported from `scipy.special`) 

pade - Pade approximation to function as the ratio of two polynomials. 

(imported from `scipy.interpolate`) 

info - Get help information for a function, class, or module. (imported from `numpy`) 

source - Print function source code. (imported from `numpy`) 

who - Print the Numpy arrays in the given dictionary. (imported from `numpy`)
