Abstract
Contourlet transform lacks shift invariance, and threshold processing on the coefficients may produce pseudo Gibbs phenomena. For recursive cycle spinning algorithm can reduce the pseudo Gibbs phenomena. This paper studies the image denoising method combined with Contourlet transform and recursive cycles pinning algorithm, The analysis show that the factor need to be adjusted. When the adjustment factor takes best value, the corresponding image objective index PSNR (Peak Signal to Noise Ratio) is the largest, and images visual effects are optimal. The experimental results show that: compared with original algorithm, changing adjustment factor, the PSNR of denoised image can be improved 0.6–1.2.
