Abstract
A fast implementation of the discrete Fourier transform (DFT) for spectral analysis of two-dimensional images is presented. The implementation time is order N, where N is the width of the image. The implementation is based on an old algorithm and a new architecture. The algorithm is the Chirp Z transform (CZT) implementation of the DFT. The architecture is a multiprocessor, mesh-connected, single-instruction, multiple-data (SIMD) scheme based on the Martin Marietta Geometric Arithmetic Parallel Processor (GAPPTM) chip. Using this implementation, image texture may be adaptively filtered for real-time image understanding applications.
