Miscellaneous routines (scipy.misc)ΒΆ
Various utilities that don’t have another home.
Note that the Python Imaging Library (PIL) is not a dependency of SciPy and therefore the pilutil module is not available on systems that don’t have PIL installed.
| ascent() | Get an 8-bit grayscale bit-depth, 512 x 512 derived image for easy use in demos The image is derived from accent-to-the-top.jpg at http://www.public-domain-image.com/people-public-domain-images-pictures/ :Parameters: None :Returns: ascent : ndarray convenient image to use for testing and demonstration .. |
| bytescale(data[, cmin, cmax, high, low]) | Byte scales an array (image). |
| central_diff_weights(Np[, ndiv]) | Return weights for an Np-point central derivative. |
| comb(N, k[, exact, repetition]) | The number of combinations of N things taken k at a time. |
