Abstract：The multi-image homomorphic filtering task is distributed and the filtering results is collected by CPU ,the given multiple images are assigned to the multiple GPUs and their thread blocks ,GPU core functions are called to execute Fourier transform and inverse Fourier transform ,and then the multi-image homomorphic filtering algorithm using CPU and GPUs cooperatively parallel computing are designed and implemented .The experimental results show that the given parallel filtering algorithms are efficient ,and compared with the parallel algorithm using single GPU computation ,the one using mul-tiple GPUs computation can remarkably reduce the running time .
