Anti-aliasing (Camcorder)

The process which helps control the appearance of aliasing on computer generated images, usually including an alteration of background coloration and blurring.

Anti-aliasing (Cinematography)

Filtering of erroneous frequencies that are created during the analog to digital conversion process. (Sound/Picture)

Anti-aliasing (Computer Graphics)

Anti-aliasing is sub pixel interpolation, a technique that makes edges appear to have better resolution.

Anti-aliasing (Computer Technology)

Technique to create more beautifull images in a lower resolution. This is most noticeable when dealing with curves, such as circles. For example, if you look at a circle drawn in a simple paint program at a low resolution, you can see the "steps" the points take to make the circle. If you use anti-aliasing, different shades of the circle's color are used to "fill in" the gaps caused by low resolution.

Anti-aliasing (Digital Imaging)

The smoothing and removing of aliasing effects by electronic filtering and other techniques, such as blending of hard edges. Also blending objects-oriented art with bit mapped art. Some current systems and hardware generators have automatic anti-alias research circuitry. Application - The highest level of software that the user sees. It is above the operating system's software level, which may be running within an environment. Also a generic term for software programs and/or developers.

Anti-aliasing (Electronic Cinematography)

A filtering process to prevent aliasing or to reduce the aliasing that is already in the signal i.e. the pre-filtering or post filtering of any data to ensure that they are suitable for the particular sampling structure being used. For instance, smoothing out diagonal lines or curved surfaces in a digitally generated wipe pattern or text from a character generator are particular cases of anti-allasing. With reference to images it commonly means prevention of jaggies. Removal of the same artifacts after sampling is usually more difficult and normally involves greater softening of the image.

Anti-aliasing (Film Production)

Filtering of erroneous frequencies that are created during the analog to digital conversion process. (Sound/Picture)

Anti-aliasing (Photography)

The process of reducing Stair-Stepping by smoothing edges where individuals pixel are visible.

Anti-aliasing (Publishing)

Rendering techniques that reduce aliasing. It determines the color value of a pixel by averaging the color value of the pixels around it. This is usually based on some form of interpolation or oversampling.

Anti-aliasing (Real Time 3D)

Anti-aliasing removes the stair-stepping or jaggies which occur at the edges of polygons or between the texels on the polygons. It works by interpolating the pixels at the edges to make the difference between two color areas less dramatic. See also aliasing, MIP mapping, texture filtering.

Anti-aliasing (Scanner)

The rendering of hard-edged objects so they blend smoothly into the background. A technique for merging object-oriented art into bitmaps.

Anti-aliasing (Technology)

This is a method used to better define higher resolution objects in lower resolution. For example, you would use anti-aliasing if you have two lines that are so close together that at 320 x 200 they look as if they are one double-width line and you want to represent them better. This is most noticeable when dealing with curves, such as circles. For example, if you look at a circle drawn in a simple paint program at a low resolution, you can see the "steps" the points take to make the circle. If you raise the resolution you'll notice the "steps" much less. If you use anti-aliasing, different shades of the circle's color are used to "fill in" the gaps caused by low resolution. A good example of this is Font Smoothing that comes with MS Plus for Windows 95.

Anti-aliasing (Typography)

Rendering techniques that reduce aliasing. It determines the color value of a pixel by averaging the color value of the pixels around it. This is usually based on some form of interpolation or oversampling.
