expn - generate image whose pixels are generated of raising to a given power pixels of the input image
output = expn(image, a, b)
- input real image
the output image whose pixels are given by `o=i^r`
Note: the values of the input image are not checked for agreement with the operation requested. For example, raising an image with negative pixel values to the power of `r=0.5` will yield incorrect results.
