2. Image compression - Wikipedia

   en.wikipedia.org/wiki/Image_compression

   Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.

3. Wikipedia : Featured picture criteria/Image size

   en.wikipedia.org/wiki/Wikipedia:Featured_picture...

   Compression of an image to reduce file size (in Kb) is usually "lossy" and is not advised for featured pictures. Image compression will reduce download times and save disk space, but it does so at the expense of fine detail and overall image quality. If in doubt, when saving JPEG files, always select the "maximum" quality setting.

4. bzip2 - Wikipedia

   en.wikipedia.org/wiki/Bzip2

   bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm.It only compresses single files and is not a file archiver.It relies on separate external utilities such as tar for tasks such as handling multiple files, and other tools for encryption, and archive splitting.

5. Template:Non-free reduce - Wikipedia

   en.wikipedia.org/wiki/Template:Non-free_reduce

   This template should be added to the oversized file. Files tagged with this template are placed in the Category:Wikipedia non-free file size reduction requests.Once an oversized file has been replaced by a reduced version, it should be tagged with {{subst:orphaned non-free revisions}}.

6. Lossy compression - Wikipedia

   en.wikipedia.org/wiki/Lossy_compression

   The primary programs for lossless editing of JPEGs are jpegtran, and the derived exiftran (which also preserves Exif information), and Jpegcrop (which provides a Windows interface). These allow the image to be cropped , rotated, flipped , and flopped , or even converted to grayscale (by dropping the chrominance channel).

7. Data compression - Wikipedia

   en.wikipedia.org/wiki/Data_compression

   Data compression aims to reduce the size of data files, enhancing storage efficiency and speeding up data transmission. K-means clustering, an unsupervised machine learning algorithm, is employed to partition a dataset into a specified number of clusters, k, each represented by the centroid of its points.

8. List of computer display standards - Wikipedia

   en.wikipedia.org/wiki/List_of_computer_display...

   Although not an official name, this term is now used to refer to 1152×864, which is the largest 4:3 array yielding less than a binary megapixel (2^20, 1048576 pixels, 1048 decimal kilopixels), thus allowing the greatest "normal" resolution at common colour depths with a standard amount of video memory (128 kB, 512 kB, 1 MB, 2 MB, etc.).

9. Display resolution standards - Wikipedia

   In Microsoft Windows operating system specifically, the larger taskbar of Windows 7 occupies an additional 16-pixel lines by default, which may compromise the usability of programs that already demanded a full 1024 × 768 (instead of, e.g. 800 × 600) unless it is specifically set to use small icons; an "oddball" 784-line resolution would ...
