An aimbot or autoaim is a type of computer game bot most commonly used in first-person shooter games to provide varying levels of automated target acquisition and calibration to the player. They are sometimes used along with a triggerbot, which automatically shoots when an opponent appears within the field-of-view or aiming reticule of the player.
Pastebin.com is a text storage site. It was created on September 3, 2002 by Paul Dixon, and reached 1 million active pastes (excluding spam and expired pastes) eight years later, in 2010. [3] It features syntax highlighting for a variety of programming and markup languages, as well as view counters for pastes and user profiles.
The most famous pastebin is the eponymous pastebin.com. [citation needed] Other sites with the same functionality have appeared, and several open source pastebin scripts are available. Pastebins may allow commenting where readers can post feedback directly on the page. GitHub Gists are a type of pastebin with version control. [citation needed]
Luminance only, Chrominance only, and full color image. Chrominance (chroma or C for short) is the signal used in video systems to convey the color information of the picture (see YUV color model), separately from the accompanying luma signal (or Y' for short).
Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two or more images or video streams together based on color hues (chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting , motion ...
Chroma is the "colorfulness of an area judged as a proportion of the brightness of a similarly illuminated area that appears white or highly transmitting". [3] [2] ...
Luma alone does not perfectly represent luminance; accurate luminance requires both accurate luma and chroma. Hence, errors in chroma "bleed" into the luminance of an image. Note the bleeding in lightness near the borders. Due to the widespread usage of chroma subsampling, errors in chroma typically occur when it is lowered in resolution ...
Chroma dots were once regarded as undesirable picture noise, but recent advances in computer technology have allowed them to be used to reconstruct the original colour signal from black-and-white recordings, providing a means to re-colour material where the original colour copy is lost. Example of the chroma dot reconstruction:
