Abstract
Combining the wavelet analysis and partial differential equations denoising method and applying synthesis algorithm applied to CT image denoising in this paper. It has some advantages: small amount of calculation, pay attention to subtle changes when denoise, highlight the local character of image, overcome the inadequacy of single wavelet transform method to a certain extent. Both theoretical analysis and simulation have verified the validity of revised method proposed in this paper.
