Deconvolution using natural image priors
If the matrix C f is a full rank matrix, and no noise is involved in the imaging process, the simplest approach to deconvolve y is to invert C f and define x = C −1 f y. Or in the frequency domain, X(ν,ω) = Y (ν,ω)/F(ν,ω) This, however, is very rarely stable enough. For example, the inverse is not defined in frequencies (ν,ω) for which F(ν,ω) = 0. Even in case |F(ν,ω)| is not exactly 0 but smal...

متن کاملFast Image Deconvolution using Hyper-Laplacian Priors
The heavy-tailed distribution of gradients in natural scenes have proven effective priors for a range of problems such as denoising, deblurring and super-resolution. These distributions are well modeled by a hyper-Laplacian ( p(x) ∝ e−k|x|α ) , typically with 0.5 ≤ α ≤ 0.8. However, the use of sparse distributions makes the problem non-convex and impractically slow to solve for multi-megapixel ...
متن کاملBlind Deconvolution via Lower-Bounded Logarithmic Image Priors
In this work we devise two novel algorithms for blind deconvolution based on a family of logarithmic image priors. In contrast to recent approaches, we consider a minimalistic formulation of the blind deconvolution problem where there are only two energy terms: a leastsquares term for the data fidelity and an image prior based on a lowerbounded logarithm of the norm of the image gradients. We s...
متن کاملGood Image Priors for Non-blind Deconvolution - Generic vs. Specific
In Fig. 1 through Fig. 5 we show the 5 groundtruth images along with their example images. These 5 images are then blurred with kernels 2, 4, 6, 8 from [1] to generate the synthetic testset of our experiments. 1% i.i.d Gaussian noise is added to the luminance channel. These images come from the dataset provided by [2]. As can be seen, the sharp example images are instance-level scene matches, w...
