A Noise-Robust Method with Smoothed \ell_1/\ell_2 Regularization for Sparse Moving-Source Mapping

open access: yes, 2016
The method described here performs blind deconvolution of the beamforming output in the frequency domain. To provide accurate blind deconvolution, sparsity priors are introduced with a smooth \ell_1/\ell_2 regularization term. As the mean of the noise in

A neural network approach for the blind deconvolution of turbulent flows

open access: yes, 2017
We present a single-layer feedforward artificial neural network architecture trained through a supervised learning approach for the deconvolution of flow variables from their coarse grained computations such as those encountered in large eddy simulations.

Blind and Non-Blind Deconvolution-Based Image Deblurring Techniques for Blurred and Noisy Image

open access: yesTikrit Journal of Engineering Sciences
: Image deblurring is a common issue in low-level computer vision aiming to restore a clear image from a blurred input image. Deep learning innovations have significantly advanced the solution to this issue, and numerous deblurring networks have been ...

Guide star based deconvolution for imaging behind turbid media

open access: yesJournal of the European Optical Society-Rapid Publications, 2018
Background If structures of interest are hidden beneath turbid layers such as biological tissues, imaging becomes challenging, even impossible. However, if the point spread function of the system is known from the presence of a guide star, application of

Adaptive Model for Magnetic Particle Mapping Using Magnetoelectric Sensors

open access: yesSensors, 2022
Imaging of magnetic nanoparticles (MNPs) is of great interest in the medical sciences. By using resonant magnetoelectric sensors, higher harmonic excitations of MNPs can be measured and mapped in space.

An Efficient Method for Non-Convex Blind Deconvolution

open access: yesIEEE Access, 2019
This paper considers blind deconvolution problem that to recover unknown signals fand g from their convolution signal. Non-convex optimization approach is an efficient method to get the solution, but it is a challenge to find the exact solution for a non-

Blind Deconvolution Using Modulated Inputs [PDF]

open access: yesIEEE Transactions on Signal Processing, 2020
This paper considers the blind deconvolution of multiple modulated signals, and an arbitrary filter. Multiple inputs $\boldsymbol{s}_1, \boldsymbol{s}_2, \ldots, \boldsymbol{s}_N =: [\boldsymbol{s}_n]$ are modulated (pointwise multiplied) with random sign sequences $\boldsymbol{r}_1, \boldsymbol{r}_2, \ldots, \boldsymbol{r}_N =: [\boldsymbol{r}_n ...

Blind deconvolution of video sequences [PDF]

open access: yes2008 15th IEEE International Conference on Image Processing, 2008
We present a new blind deconvolution method for video sequence. It is derived following an inverse problem approach in a Bayesian framework. This method exploits the temporal continuity of both object and PSF Combined with edge-preserving spatial regularization, a temporal regularization constrains the blind deconvolution problem, improving its ...
