Any visible result of a procedure which is caused by the procedure itself and not by the entity being analyzed. Common examples include histological structures introduced by tissue processing, radiographic images of structures that are not naturally present in living tissue, and products of chemical reactions that occur during analysis.

Artificial features introduced in the course of processing.

Unwanted elements in the video image resulting from video signal transmission.

Artifacts are defined as unwanted visible effects in the picture caused by disturbances and errors in the video transmission or digital processing. Artifacts include "edge crawl" or "dot crawl" or "hanging dots" in analog pictures, and "pixelation", "contouring" or "blockiness" in digital pictures.

The distortion of a digital video image caused by such factors as errors, loss of information, or computer processes during decompression. Common artifacts are blocks of large pixels or the presence of jerky motion in playback.

Visual effects (usually thought of as defects) introduced into a digital image in the course of scanning or compression that do not correspond to the image scanned.

Unusual or unwanted video distortion. Examples of artifacts include flicker, jitter, degradation of resolution, and aspect ratio abnormalities.

Unwanted aberrations in the image such as blotches [from over compression], Christmas tree lights [multi colored speckles from bright highlights], noise [granularity from underexposure] and other unwanted effects that sometimes afflict digicam images.

There are many types of artifacts apparent on DVD. They range from MPEG2 Compression artifacts introduced by the encoding process to film artifacts which could include dust or scratches on the original print. The higher resolution on DVD also shows up weaknesses in the original print - a good print will always look fantastic on DVD, a poor print could look pretty bad. Artifacts can also be introduced by the downconversion of an Anamorphic source.

Undesirable elements or defects in a video picture. Most common in digital are macroblocks, which resemble pixelation of the video image, and pops and clicks in audio.

Defects in the video signal, usually caused by compression errors.

mental The notations of the mind, the snippets of advice, the quotations, facts and figures, rules and formulae, vocabulary terms, musical phrases, identified colors and smells, which are the more or less formed and established items in our express awareness. Clearly formulated emotions, images, ideas, musical phrases, verbal constructions (words, phrases, sentences), which can be identified, related to other elements in awareness, and communicated.

Unwanted visible effects in the picture created by disturbances in the transmission or image processing, such as 'edge crawl' or 'hanging dots' in analog pictures, or 'pixelation' in digital pictures.

Artifacts are visible corruption of the image or undesirable elements or defects in a video picture created by disturbances in the video transmission or processing. These may occur naturally in the video process but must be eliminated to produce a high quality picture. The most common reasons for video artifacts are cross color and cross luma. Examples include "dot crawl" or "hanging dots" in analog pictures, or "pixelation" in digital pictures.

Image imperfections caused by compression.

Undesirable elements or defects in a video picture. These may occur naturally in the video process and must be eliminated in order to achieve a high-quality picture. The most common are cross-color and cross-luminance.

Defects commonly occuring in digital as macro block resembling as pixelation of the video image.

These are flaws in a picture such as jitter, blocking, or ghosts.

(Artifacting), Misinterpreted or extraneous digital information resulting from the technical limitations of an imaging system. Artifacts alter pixel values, and are the results of flare, motion, compression, dust, scratches, and so on. Artifacts create colors faults or line faults that visibly impact the image negatively.

Unwanted visual distortions that appear in a video image, such as cross-color artifacts, cross-luminance artifacts, jitter, blocking, ghosts, etc.

Imperfections in the DTV signal, known as "glitches" in analog television. The most common artifacts are small black or white blocks in the picture, called "pixilation", or pops and clicks in the audio.

Unwanted visible effects in a picture created by disturbances in the transmission or image processing, for example "edge crawl" or "hanging dots" in analog pictures, or "pixelation" in digital images.

Flaws in video caused during conversion to DVD, often by trying to compress too much information on to the disc.

Noticeable loss of video and/or audio fidelity in a broadcast or recording caused by limitations in the technology used. Usually reflects undesirable distortion(s) of the original when digitized.

Unwanted differences from the original image caused by lossy image compression. With lossy image compression, the more compression, the more artifacts are visible.

Sometimes spelled "artefacts" - Picture degradations that occur as a result of image-processing tasks, such as compressing an image which can result in an increase in digital "noise".

Unwanted visible effects in the picture created by disturbances in the video transmission or processing. Examples include "dot crawl" or "hanging dots" in analog pictures, or "pixelation" in digital pictures.

are visual digital effects introduced into an image during scanning that do not correspond to the original image being scanned. Artifacts might include pixellation, dotted or straight lines, regularly repeated patterns, moire, etc.

In graphics, persistent portions of images resulting from improper blitting operations.

Objects that give us information about another culture or time.

an object produced or shaped by a human, especially a tool, a weapon, or an ornament of archaeological or historical interest

Something created by humans for a practical purpose. Artifact usually refers to an object remaining from a particular period, such as fire helmet from the 1800s.

Use of physical objects; ex: staring at watch to indicate impatience, or visual aides.

objects made by humans, such as stone tools; studied by geoarcheologists.
