Abstract: A CS-based multiframe denoising algorithm in Contourlet domain is proposed.We exploit the state-space relationship among the sequential images to build a novel CS-based framework to reduce noise.By estimating state-space relationship among the inter-frames,the successive frames are denoised in Contourlet domain and used weighted average to get a restored image.Experiments demonstrate the effectiveness of the proposed method and show the superiority for various noise characteristics,especially in preserving the detail and texture information with higher PSNR values.
