An artifact is the error or misrepresentation introduced by a technique and/or technology. For example a poor pseudo-random number generator would introduce artifacts into statistical research models.
Types
- Synthesis: an element is produced from, but is neither a part of the technique nor of the subject. For an example see "Sampling sinusoidal functions" in aliasing
Examples
Artifacts of this kind include, but are not limited to:
- Artifact (medical imaging), misrepresentations of tissue structures seen in medical images
- Artifact (observational), any perceived distortion or other data error caused by the instrument of observation
- Compression artifact, data compression artifact in computer science, resulting from lossy data compression
- Digital artifact, a visible defect in a digital photo or video picture
- Sonic artifact, in sound and music production, sonic material that is accidental or unwanted, resulting from the editing of another sound
