8 The SVD Applied to Signal and Image Deblurring
نویسنده
چکیده
We will discuss the restoration of one-dimensional signals and two-dimensional gray-scale images that have been contaminated by blur and noise. After an introduction on the representation of images, we describe how the SVD can be applied to restore one-dimensional signals. However, this restoration approach cannot be applied in a straightforward manner to two-dimensional images that have been contaminated by blur and noise, due to the large computational burden. We discuss how the problem can be simplified to allow deblurring of two-dimensional gray-scale images with the aid of the SVD.

Blind Image Deblurring Using Row-Column Sparse Representations
Blind image deblurring is a particularly challenging inverse problem where the blur kernel is unknown and must be estimated en route to recover the deblurred image. The problem is of strong practical relevance since many imaging devices such as cellphone cameras, must rely on deblurring algorithms to yield satisfactory image quality. Despite significant research effort, handling large motions r...

متن کاملNon-uniform Single Image Deblurring Based on Sparse Representation and Adaptive Dictionary Learning
Considering the sparseness property of images, a sparse representation based iterative deblurring method is presented for single image deblurring under uniform and non-uniform motion blur. The approach taken is based on sparse and redundant representations over adaptively training dictionaries from single blurred-noisy image itself. Further, the K-SVD algorithm is used to obtain a dictionary th...

In this paper, a steganography technique for JPEG2000 compressed images using singular value decomposition in wavelet transform domain is proposed. In this technique, DWT is applied on the cover image to get wavelet coefficients and SVD is applied on these wavelet coefficients to get the singular values. Then secret data is embedded into these singular values using scaling factor. Different com...
