Miscellaneous routines (scipy.misc)¶
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 |
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. |
derivative(func, x0[, dx, n, args, order]) | Find the n-th derivative of a function at a point. |
face([gray]) | Get a 1024 x 768, color image of a raccoon face. |
factorial(n[, exact]) | The factorial function, n! = special.gamma(n+1). |
factorial2(n[, exact]) | Double factorial. |
factorialk(n, k[, exact]) | Multifactorial of n of order k, n(!!...!). |
fromimage(im[, flatten, mode]) | Return a copy of a PIL image as a numpy array. |
imfilter(arr, ftype) | Simple filtering of an image. |
imread(name[, flatten, mode]) | Read an image from a file as an array. |
imresize(arr, size[, interp, mode]) | Resize an image. |
imrotate(arr, angle[, interp]) | Rotate an image counter-clockwise by angle degrees. |
imsave(name, arr[, format]) | Save an array as an image. |
imshow(arr) | Simple showing of an image through an external viewer. |
info([object, maxwidth, output, toplevel]) | Get help information for a function, class, or module. |
lena() | Function that previously returned an example image |
logsumexp(a[, axis, b, keepdims, return_sign]) | Compute the log of the sum of exponentials of input elements. |
pade(an, m) | Return Pade approximation to a polynomial as the ratio of two polynomials. |
toimage(arr[, high, low, cmin, cmax, pal, ...]) | Takes a numpy array and returns a PIL image. |
source(object[, output]) | Print or write to a file the source code for a Numpy object. |
who([vardict]) | Print the Numpy arrays in the given dictionary. |
