A Novel Approach to SVD-Based Image Filtering Improvement
2008
2008 International Conference on Computer Science and Software Engineering
Preserved Fulltext
Image filtering based on SVD favors the denoising in the line (horizontal) and column (vertical) direction. Based on this property, a novel approach to improving the filtering efficiency of a noisy image is proposed in this paper. The new denoising method adapts shape and size of block to local orientation before performing SVD filtering. Through over-complete representation in overlap regions; the proposed method performs well in denoising and preserving image details. This new technique makes
