| Abstract: | The fundamentals,implementation process and characteristic of homomorphc filtering method are introduced based on the illumination and reflection model.The suitable filter and the expression are produced.Then the homomorphic filtering method is proposed based on the wavelet transform to carry on processing to the wavelet decomposition coefficient. |
