Parametric model for image blur kernel estimation
2018 International Conference on Orange Technologies (ICOT), 2018This paper we propose an novel parametric approach for single image kernel estimation with both motion blur and Gaussian blur coupled. In the view of that daily pictures captured by handheld device usually contain motion blur and defocus simultaneously.

Blur Kernel Estimation by Structure Sparse Prior [PDF]
Blind image deblurring tries to recover a sharp version from a blurred image, where blur kernel is usually unknown. Recently, sparse representation has been successfully applied to estimate the blur kernel.

Multi-Frame Blind Super-Resolution Based on Joint Motion Estimation and Blur Kernel Estimation
Multi-frame super-resolution makes up for the deficiency of sensor hardware and significantly improves image resolution by using the information of inter-frame and intra-frame images.

Multiregression spatially variant blur kernel estimation based on inter‐kernel consistency
Most single‐image super‐resolution (SR) models suffer from the degradation of image restoration performance when restoring a high‐resolution (HR) image from a low‐resolution (LR) image downscaled using an unknown blur kernel. The spatially invariant blur

Robust Motion Blur Kernel Estimation by Kernel Continuity Prior [PDF]
The accurate kernel estimation is key to the blind motion deblurring. Many previous methods depend on the image regularization to recover strong edges in the observed image for kernel estimation.

Convergence Analysis of MAP Based Blur Kernel Estimation [PDF]
One popular approach for blind deconvolution is to formulate a maximum a posteriori (MAP) problem with sparsity priors on the gradients of the latent image, and then alternatingly estimate the blur kernel and the latent image. While several successful MAP based methods have been proposed, there has been much controversy and confusion about their ...

Blur kernel estimation approach to blind reverberation time estimation [PDF]
Reverberation time is an important parameter for characterizing acoustic environments. It is useful in many applications including acoustic scene analysis, robust automatic speech recognition and dereverberation. Given knowledge of the acoustic impulse response, reverberation time can be measured using Schroeder's backward integration method.
