| Abstract: | Wavelet transform is a very important digital signal processing method. It is emphasized on the wavelet theory and its application in image processing, aimed to show the application and foreground of the wavelet transform in the denoising of image field. By comparing the De-noise method of Fourier transform and Wavelet transform,we can find that the primary feature of wavelet analysis is to provide the part meticulous and analytic function and such de-noising method is strongly useful in practice and worth spreading. |
