Digital Image Processing

-
Image
  Image processing is the process of manipulating digital images. See a list of image processing techniques, including image enhancement, restoration, & others. Digital image processing is the use of a digital computer to process digital images through an algorithm. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and distortion during processing. Since images are defined over two dimensions or more, digital image processing may be modeled in the form of multidimensional systems.  The generation and development of digital image processing are mainly affected by three factors: first, the development of computers; second, the development of mathematics (especially the creation and improvement of discrete mathematics theory); and third, the demand for a wide range ...

The World Of Linux

-
Image
Linux is an open source operating system (OS). It was originally conceived of and created as a hobby by Linus Torvalds in 1991 . Linus, while at university, sought to create an alternative, free, open source version of the MINIX operating system, which was itself based on the principles and design of Unix. That hobby has since become the OS with the largest user base, the most-used OS on publicly available internet servers, and the only OS used on the top 500 fastest supercomputers.  Perhaps the best thing about Linux is that it's open source. Linux is released under the GNU General Public License (GPL). That means that anyone can run, study, share, and modify the software. The modified code can also be redistributed, and even sold, but must be done so under the same license. This differs greatly from traditional operating systems—Unix and Windows, for example—which are proprietary, locked-down, and delivered as-is and unmodifiable. From smartphones to cars, supercomputers and h...
