ABSTRACT:: 
Discrete-time fractional derivative filters (1-D and 2-D) are shown to
be well approximated from a small set of integer derivatives. A
fractional derivative of arbitrary order (and, in 2-D, of arbitrary
orientation) can therefore be efficiently computed from a linear
combination of integer derivatives of the underlying signal or image.
