Abstract: The edge and outline of image arc very useful in the pattern recognition. But there arc much difficulties if the signals are polluted by noise. We first introduced the multiscale geometric analysis theory, and then proposed a method for image denoising on scale factor and contourlet transform. Experiments show that the performance of the proposed method is obviously superior to other methods both in vision and in SNR.
Key words: Multiscale geometric analysis,Contourlet transform,Scale factor,Image denoising
