Histogram Specification
Histogram Specification essentially gives us the capability
to change the histogram of a image to any specified histogram.
Here the specified histogram is taken from an image.
However this process is a little inaccurate on account of the grey levels
which may be missing from the specified histogram
and due to rounding of errors in computing the inverse transfer function.

As can be seen the resulting image is not an exact
copy of the specified histogram. This is so because of rounding off errors
and the missing grey levels in the specified histogram. This can be rectified
by an interactive specification of the specified histogram.
