Definition of anti-aliasing in English English dictionary
AA Hides the jagged effect of image diagonals by modulating the intensity on either side of the diagonal boundaries This creates a local blurring along these edges and reduces the appearance of stepping The result is a smoother, far more realistic image Also see: Real-Time Full-Scene HW Anti-Aliasing
Technique used in imaging applications to alleviate the jagged appearance of graphics produced on low-resolution devices such as computer monitors Neutral colour is interpolated between two colour planes
One solution to the *aliasing problem The pixels of the graphic being displayed are shaded by analysing them as areas (not dimensionless points) on a theoretical infinite *resolution output surface In practice it's adequate to resample on a grid 2 to 16 times as fine as the original device grid - meaning 5 to 257 grey levels respectively See the TrueType Anti-Aliasing page
In computer graphics, the smoothing of the jagged, "stairstep" appearance, known as aliasing, in graphical elements such as diagonal lines, curves, and circles Aliasing occurs when the resolution of an image is too coarse to achieve the appearance of a smooth line or curve Anti-aliasing software routines can blur the roughness of a jagged edge by shading or coloring neighboring pixels to make the transition between light and dark (or between two colors) less distinct and therefore less immediately visible
A technique that smooths the roughness in images or sound caused by aliasing During frequency sampling, aliasing generates a false (alias) frequency along with the correct one With images this produces a stair-step effect Anti-aliasing corrects this by adjusting pixel positions or setting pixel intensities so that there is a more gradual transition between pixels
Smoothing the jaggy edges of selection or paint tools in digital imaging applications
Removing alias frequencies from the sampled signal In letterfoms, jaggedness can be minimized during reconstruction by using various grey levels at the edges of stokes
A method to remove the jagged edges of objects It looks very good, but is not supported in FS98, because so few cards do anti-aliasing without a performance decrease Can be done with brute force by rendering a scene at 1600x1200 then downsampling to 800x600 (at the cost of performance), or cleverly by antialiasing each edge (at the cost of developing hardware that does this fast) Here is a very-nicely anti-aliased scene, using the PixelSquirt chipset
In audio applications, the smoothing of steps between discrete samples to reduce the undesirable effects of low bit-rate capture
Smoothing or blending the transition of pixels in an image Anti-aliasing the edges on a graphic image makes the edges appear smooth, not jagged
The process of reducing stair-stepping by smoothing edges where individual pixels are visible
A form of interpolation used in graphics display technology when combining images; pixels along the transitions between images are averaged to provide a smooth transition
[ed: this is an 'off-the-cuff' definition, feel free to clarify it for me ;-) ] On low-resolution bitmap devices (where ragged, ugly characters are the norm) which support more than two colors, it is possible to provide the appearance of higher resolution with anti-aliasing Anti-aliasing uses shaded pixels around the edges of the bitmap to give the appearance of partial-pixels which improves the apparent resolution
A software process to smooth out the jagged appearance of lines in a bit-mapped image
A remarkable Acorn invention to improve display of outline fonts, where the edges are made fuzzy, blending to the background This process can also be applied to vector graphics, whereby lines and curves are smoothed, rather than having the classic computer staircase effect The logo above is fully anti-aliased The following images, using the same font, illustrate the poor text display of a Windows™ PC, despite being in a 32-bit screen mode, when compared to the RISC OS display - which matches the printed document as closely as possible: PC: Acorn
When combining images in graphics-display technology, AA is a form of interpolation The combination averages the pixels along the transitions between images to provide a smooth transition
A technique that is used to smooth curves and diagonal lines by adding pixels of intermediate shades or colors around the line
Smooths out the step-like rough edges of a line by blending the colours of the pixels that make up that line with surrounding colours
Anti-aliasing is the process of making diagonal or curved lines appear smooth and continuous in computer-generated images Images on a computer screen are made up of tiny squares, or pixels When these are in a straight line, they have straight smooth edges, but when they are placed at an angle or curve to each other they can appear jagged Anti-aliasing fills in data between the pixels by adding pixels of intermediate color values to to blend the edge, improving its appearance Anti-aliasing also adds more colors to the image making it less compressible and therefore larger
A technique for smoothing out jaggiesthe jagged edges on diagonal lines and curves on-screen To compensate, graphics cards blur the edges by adding various shades of gray or color to surrounding pixels (this is called dithering)
Anti-aliasing is a technology used to resize bitmaps which you may have noticed as "fuzziness" on an image Imagine you are resizing a graphic of black text on a white backgroundas you resize it up and down the software has to decide whether to make the new pixels black or white, which can produce a jagged appearance What anti-aliasing does instead is put in a gray pixel, which produces a smoother transition, even though it does add a little fuzziness
In computer imaging, a blending effect that smoothes sharp contrasts between two regions-e g , jagged lines or different colors This reduces the jagged edges of text or objects In voice signal processing, it refers to the process of remov-ing or smoothing out spurious frequencies from waveforms produced by convert-ing digital signals back to analog
In computer graphics, the smoothing of the jagged, "stairstep" appearance of graphical elements See also jaggies
The method in which jagged lines in 3d environments (easily seen in the horizon of games) are removed and smoothed out for a picture that is easier on the eyes
A technique used to make diagonal or curved edges appear smoother by setting pixels near the edge to intermediate colors according to where the edge crosses the underlying color
Antialiasing is a method of reducing or preventing aliasing artifacts when rendering by using color information to simulate higher screen resolutions In one technique, blurred pixels are introduced by filtering the image, or individual elements, to remove spatial frequencies that are greater than the pixel sample rate by convolution If high frequencies remain they may cause other visual artifacts such as Moiré patterns An alternative and often preferable technique is supersampling, where many samples per pixel are estimated and combined
The process that gives the illusion of smoothing the pixelated (or jagged) edges in a graphic image by intermixing pixels of the adjoining colors along the edges of the graphic
Techniques used to smooth the "jaggies" otherwise found on lines and polygon edges caused by scan conversion Common techniques include adjusting pixel positions or setting pixel intensities according to the percent of pixel area coverage at each point
Any technique that reduces sampling artifacts in the final image, particularly "jaggies" caused by abrupt changes in scene geometry The usual antialiasing method used in Radiance is called supersampling
A method of smoothing the jagged edges along the lines and curves of text or graphics This is done by a mathematical process that supersamples pixels Aliasing is caused by limited display resolution Aliasing effects include staircasing along diagonal lines, moiré effects in checkerboards, and temporal aliasing (strobing) in animated scenes
A software technique used for diminishing the appearance of jagged edges in raster graphic images that should be smooth in appearance It reduces the prominence of jagged edges by surrounding the edges with intermediate shades of gray or color
(n ) In computer graphics, the process of smoothing stair-step lines and curves, either by using a higher-resolution device or software routines that shade surrounding pixels and lessen the visual distinction
A method of softening sometimes jagged edges on bitmapped images by creating a gradual transition between one value and another Often used on type so that it doesn't look rough and pixelated
Antialiasing is the smoothing of the image roughness caused by aliasing Methods include adjusting pixel positions or setting pixel intensities so that there is a more gradual transition between the color of a line and the background color
