imread(name, flatten=0)
Read an image file from a filename.
Optional arguments:
•flatten (0): if true, the image is flattened by calling convert(‘F’) on
the resulting image object. This flattens the color layers into a single grayscale layer.
imrotate(arr, angle, interp=’bilinear’)
Rotate an image counter-clockwise by angle degrees.
Interpolation methods can be:
‘nearest’ : for nearest neighbor ‘bilinear’ : for bilinear ‘cubic’ or ‘bicubic’ : for bicubic
imresize(arr, size)
Resize an image.
If size is an integer it is a percentage of current size. If size is a float it is a fraction of current size. If size is a
tuple it is the size of the output image.
imshow(arr)
Simple showing of an image through an external viewer.
imfilter(arr, ftype)
Simple filtering of an image.
type can be:
‘blur’, ‘contour’, ‘detail’, ‘edge_enhance’, ‘edge_enhance_more’, ‘emboss’, ‘find_edges’, ‘smooth’,
‘smooth_more’, ‘sharpen’
factorial(n, exact=0)
n! = special.gamma(n+1)
If exact==0, then floating point precision is used, otherwise exact long integer is computed.
Notes:
• Array argument accepted only for exact=0 case.
• If n
