Pointwise Shape-Adaptive DCT for High-Quality Denoising and Deblocking of Grayscale and Color Images
The shape-adaptive discrete cosine transform (SA-DCT) transform can be computed on a support of arbitrary shape, but retains a computational complexity comparable to that of the usual separable block- DCT. Expand

BM3D Image Denoising with Shape-Adaptive Principal Component Analysis
We propose an image denoising method that ex- ploits nonlocal image modeling, principal component analysis (PCA), and local shape-adaptive anisotropic estimation. The nonlocal modeling is exploitedExpand

BM3D Frames and Variational Image Deblurring
In this paper, we construct analysis and synthesis frames, formalizing BM3D image modeling, and use these frames to develop novel iterative deblurring algorithms. Expand

Practical Poissonian-Gaussian Noise Modeling and Fitting for Single-Image Raw-Data
We present a simple and usable noise model for the raw-data of digital imaging sensors, which gives the pointwise standard-deviation of the noise as a function of the expectation of the pixel raw data output. Expand

Color Image Denoising via Sparse 3D Collaborative Filtering with Grouping Constraint in Luminance-Chrominance Space
We propose an effective color image denoising method that exploits filtering in highly sparse local 3D transform domain in each channel of a luminance-chrominance color space. Expand

Image denoising with block-matching and 3D filtering
We present a novel approach to still image denoising based on effective filtering in 3D transform domain by combining sliding-window transform processing with block-matching. We process blocks withinExpand

Image restoration by sparse 3D transform-domain collaborative filtering
We propose an image restoration technique exploiting regularized inversion and the recent block-matching and 3D filtering (BM3D) denoising filter to improve the regularization after inversion in discrete Fourier domain. Expand
