To overcome the Contourlet transform non translation invariance and spectrum aliasing defects,this paper presents a method based on nonsubsampled Contourlet transform for medical CT image denoising method.The noisy CT images are conducted by nonsubsampled Contourlet transform.Transform coefficients are obtained from different scales and different directions.Using Context model,subband of each scale and each direction is graded.Different classification uses the corresponding threshold denoising… CONTINUE READING
