Nonnegative least-squares image deblurring: improved gradient projection approaches
The least-squares approach to image deblurring leads to an ill-posed problem. The addition of the nonnegativity constraint, when appropriate, does not provide regularization, even if, as far as we know, a thorough investigation of the illposedness of the resulting constrained least-squares problem has still to be done. Iterative methods, converging to nonnegative least-squares solutions, have b...
متن کاملDictionary Construction for Patch-to-Tensor Embedding
The incorporation of a matrix relations, which encompass multidimensional similarities between local neighborhoods of data points in the underlying manifold of a data, improves the utilization of kernel based data analysis methodologies. However, the utilization of multidimensional similarities results in a larger kernel and hence the computational complexity of the corresponding spectral decom...
متن کاملGaussian Blurring-Deblurring for Improved Image Compression
The deblurring of Gaussian blur by inverting the action of the diffusion equation has long been known. This technique is interesting but without much practical application since the images have to be blurred by convolution with a Gaussian to be "de-blur-able" with this technique. In this paper we investigate the possibility to use this blurring-deblurring process as a pre-post-processing step i...
متن کاملCombining total variation and wavelet packet approaches for image deblurring
We show in this paper two ways to combine wavelet packets and total variation based deblurring methods. For this purpose, we first recall that it is possible to approximate a convolution by mean of an operator diagonal in a wavelet packet basis. Then, we show two possibilities, which uses this property, for combining wavelet packets and total variation approaches. We then show on experiments th...
متن کاملDictionary Learning for Deblurring and Digital Zoom
This paper proposes a novel approach to image deblurring and digital zooming using sparse local models of image appearance. These models, where small image patches are represented as linear combinations of a few elements drawn from some large set (dictionary) of candidates, have proven well adapted to several image restoration tasks. A key to their success has been to learn dictionaries adapted...
