Multichannel SVD-based image de-noising

: - In this paper, we propose a multichannel SVD-based image de-noising algorithm. The IntDCT is employed to decorrelate the image into sixteen subbands. The SVD is then applied to each of the subbands and the additive noise is reduced by truncating the eigenvalues. The simulation results illustrate that this technique can effectively filter the noisy images without assuming any statistics of the image by using data compression technique. Key-Words: - Singular value decomposition, integer discrete cosine transform, de-noising, preprocessing, image restoration, knee point, JPEG-LS.
