feh is a lightweight image viewer aimed mainly at users of command line interfaces. [5] [6] Unlike most graphical image viewers, feh does not have any graphical control elements (apart from an optional file name display) which enables it to also be used to display background images on systems running the X window system. feh offers six different operational modes which can be controlled via ...
The most straightforward and a conventional technique for image restoration is deconvolution, which is performed in the frequency domain and after computing the Fourier transform of both the image and the PSF and undo the resolution loss caused by the blurring factors. Nowadays, photo restoration is done using digital tools and software to fix ...

TestDisk is a free and open-source data recovery utility that helps users recover lost partitions or repair corrupted filesystems. [1] TestDisk can collect detailed information about a corrupted drive, which can then be sent to a technician for further analysis.
The Richardson–Lucy algorithm, also known as Lucy–Richardson deconvolution, is an iterative procedure for recovering an underlying image that has been blurred by a known point spread function. It was named after William Richardson and Leon B. Lucy, who described it independently. [1] [2]
Introduced by William Benoit, image restoration theory (also known as image repair theory) outlines strategies that can be used to restore one's image in an event where reputation has been damaged. Image restoration theory can be applied as an approach for understanding both personal and organizational crisis situations.
He is known for developing image repair theory (originally called "Image Restoration") and for applying it to anecdotes in various real-world contexts. [5] He was the editor of the Journal of Communication from 2003 to 2005, and of Communication Studies from 2007 to 2009.
In version control systems, a repository is a data structure that stores metadata for a set of files or directory structure. [1] Depending on whether the version control system in use is distributed, like Git or Mercurial, or centralized, like Subversion, CVS, or Perforce, the whole set of information in the repository may be duplicated on every user's system or may be maintained on a single ...
