A Method of Using GPU to Accelerate Homomorphic Filter

In order to speed up the enhancement of non-uniform illumination image, a parallel homomorphic filter method based on GPU is presented.According to the parallelity of the algorithm, employing the CUDA programming framework, homomorphic filter based on GPU was implemented.Using various resolution images as test dataset, compared the computational efficiency of CPU and GPU.The experiment result shows that GPU can effectively implement the fast algorithm.
