1 Introduction
In this paper we investigate parallel implementations of
the well known twodimensional Fast Fourier Transform
(FFT) algorithm. 1 The FFT may be taken as a key algo
rithm representing a wide class of algorithms used in im
age processing and pattern recognition that are realized
with a similar algorithmic structure. Examples within
this class include the fast Walsh transform, translation
invariant transforms for position invariant feature ex
traction in gray scale images, fast parallel sorting, etc.
