Noun( plural artifacts). An made or shaped by human hand. (archaeology) An object, such as a, or, of or interest, especially such an object found at an archaeological excavation.

The dig produced many Roman artifacts. Something viewed as a product of human or rather than an element. A or finding in an experiment or investigation that is not a true feature of the object under observation, but is a result of external action, the test arrangement, or an experimental error. The spot on his lung turned out to be an artifact of the X-ray process. An made or shaped by some agent or intelligence, not necessarily of direct human origin. (computing) A that appears in a digital image, audio or video file as a result of applying a compression algorithm. This JPEG image has been so highly compressed that it has too many unsightly compression artifacts, making it unsuitable for the cover of our magazine.

(1) Any element in a software development project. It includes documentation, test plans, images, data files and executable modules.(2) A distortion in an image or sound caused by a limitation or malfunction in the hardware or software. Artifacts may or may not be easily detectable. Under intense inspection, one might find artifacts all the time, but a few pixels out of balance or a few milliseconds of abnormal sound often go undetected.Analog ArtifactsIn film, artifacts such as blotches, scratches and flicker are commonly found, especially in older movies. Imperfections in the camera lenses and silver-grain film itself can generate 'noise,' which appears as tiny background specks, making the image softer. The electronic recording of analog videotapes can introduce noise as well.

See.Digital ArtifactsArtifacts are a natural byproduct of digital compression methods such as JPEG and MPEG, which permanently discard pixels. The greater the compression used, the more artifacts are likely, and fast motion sequences are a major contributor. As TV screens become larger, the distortions are more noticeable. In digital cameras, artifacts may arise when performing digital zoom. When analog material is converted to digital, tiny discrepancies (quantization errors) may result.

Contents.Context Artifacts can come from any or source such as:. along with a. From any such as a or other domestic setting., such as atArtifacts are distinguished from the main body of the archaeological record such as, which are non-portable remains of human activity, such as, deposits, trenches or similar remains, and from or ecofacts, which are objects of archaeological interest made by other organisms, such as or.Natural objects that humans have moved but not changed are called. Examples include seashells moved inland, or rounded pebbles placed away from the water action that made them. Obverse, Jomsborg, 980s, Burial site of kingThese distinctions are often blurred; a bone removed from an animal carcass is a biofact but a bone carved into a useful implement is an artifact. Similarly there can be debate over early stone objects that could be either crude artifacts or naturally occurring and happen to resemble early objects made.

It can be difficult to distinguish the differences between actual man-made artifacts and – naturally occurring lithics that resemble man-made tools. It is possible to authenticate artifacts by examining the general characteristics attributed to man-made tools and local characteristics of the site.In ethnography and archaeology, a category of 'ancestral artifact' has been proposed, defined as 'any object of natural raw material (chert, obsidian, wood, bone, native copper, and so on) made by a people following a lifestyle based on foraging (e.g. Hunting, gathering) and/or basic agriculture or pastoralism (e.g. Horticulture, transhumance)'.
