Hardware implementation of GCFD for color images recognition

The aim of this paper is to present the use of Fourier descriptors for color images recognition. We are interested in the generalized Clifford Fourier descriptors (GCFD).We Present these family of descriptors, evaluate its performance by its application to color images using a pure software implementation. This implementation does not meet the real time constraint where the need for hardware implementation in order to speed up the recognition system. So we seek a better partitioning of our system in two-part HW / SH. The design and implementation of GCFD on XILINX FPGA by exploiting FFT IP are detailed in two different architectures.
