Deblurring an image using Wiener deconvolution. Deblurring is the process of removing blurring artifacts from images. Deblurring recovers a sharp image S from a blurred image B, where S is convolved with K (the blur kernel) to generate B. Mathematically, this can be represented as = (where * represents convolution).
The only censorship by the community of note is the decision to blacklist certain images and restrict the visibility of various articles. Depictions of Muhammad, which cause offence to some Muslims, have not been censored. A number of methods can be used to prevent a computer from showing images contained in Wikipedia.
More advanced techniques of wordfilter evasion include the use of images, using hidden tags, or Cyrillic characters (i.e. a homograph spoofing attack). Another method is to use a soft hyphen. A soft hyphen is only used to indicate where a word can be split when breaking text lines and is not displayed.
Image processing techniques are performed either in the image domain or the frequency domain. 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 ...
The hashing method initially relied on converting images into a black-and-white format, dividing them into squares, and quantifying the shading of the squares, [5] did not employ facial recognition technology, nor could it identify a person or object in the image.
Sauer, the C3P tipline director, said that the group has seen an increase in reports of luring children that involve Discord, which may be attractive to people looking to exploit children given ...
The CGI proxy server pulls the ultimate destination information from the data embedded in the HTTP request, sends out its own HTTP request to the ultimate destination, and then returns the result to the proxy client. A CGI proxy tool's security can be trusted as far as the operator of the proxy server can be trusted.
This is a list of notable websites that have been blocked or censored in Russia, including current and past blocks. The Federal Service for Supervision of Communications, Information Technology and Mass Media (Roskomnadzor) has maintained an official mandatory list since 2012.
