Dual-Channel Contrast Prior for Blind Image Deblurring

IEEE Access, 2020
In this article, a dual-channel contrast prior (Dual-CP) is proposed for blind image deblurring. The prior is motivated by the observation that image contrast will significantly degenerate after the blurring process, which is proved in both ...

Fast Weighted Total Variation Regularization Algorithm for Blur Identification and Image Restoration

IEEE Access, 2016
Images obtained from unconstrained environments may be blurred by unknown kernels and affected due to noise. This paper presents a new total variation minimization-based method for blindly deblurring such images. Unlike the alternating optimization-based

Improved conditional diffusion model for image super‐resolution

IET Image Processing, Volume 19, Issue 1, January/December 2025.
Our article introduces a diffusion model based on Mean‐Reverting Stochastic Differential Equations (SDE), leveraging ENAFBlocks to enhance noise prediction performance compared to traditional ResBlocks. The Mean‐Reverting SDE utilizes low‐resolution images as means to mitigate diffusion model randomness, while an LR Encoder captures hidden information ...

Plenoptic Image Motion Deblurring

, 2018
We propose a method to remove motion blur in a single light field captured with a moving plenoptic camera. Since motion is unknown, we resort to a blind deconvolution formulation, where one aims to identify both the blur point spread function and the ...

Arbitrarily shaped Point Spread Function (PSF) estimation for single image blind deblurring [PDF]

, 2020
The research paper focuses on a challenging task faced in blind image deblurring (BID). It relates to the estimation of arbitrarily shaped (nonparametric or complex shaped) point spread functions (PSFs) of motion blur caused by camera handshake.
