A compression artifact (or artefact) is the result of an aggressive data compression scheme applied to an image, audio, or video that discards some data that may be too complex to store in the available data-rate, or may have been incorrectly determined by an algorithm to be of little subjective importance, but is in fact objectionable to the viewer. Artifacts are often a result of the latent errors inherent in lossy data compression. Datamoshing is a technique of video editing employed in video art and music videos which deliberately exploits these compression artifacts.
