11-8 A Near Focal-Plane Fourier Transform Processor using Bit-Serial Column Parallel Processing

Abstract

The information acquired by executing Fourier transform of Image is very useful for many applications such as fingerprint identification, face identification, and various machine vision applications. However, two-dimensional Fourier transform requires tremendous computational power. In this paper, we propose a near focal-plane Fourier transform processor using bit-serial column parallel processing architecture for the high-speed calculation. In the case of 256×256-point DFT, processing time is estimated to be 0.99ms at clock frequency of 100MHz.
