- 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`)
