Image recognition system using an optical Fourier transform on a dynamically reconfigurable vision architecture

Recently, several varieties of image recognition systems using Fourier transform have been proposed. The salient benefit of using a Fourier transform is its position-independent image recognition capability. However, the operation of Fourier transform of high-resolution images is an extremely heavy operation. This paper therefore presents a proposal of image recognition systems using an optical Fourier transform on a dynamically reconfigurable vision architecture. This proposed system can recognize numerous images within an extremely short period using dynamic reconfiguration.
