Class Information
Number: 382/275
Name: Image analysis > Image enhancement or restoration > Artifact removal or suppression (e.g., distortion correction)
Description: Subject matter directed to correcting undesirable image characteristics such as spatial distortion (i.e. subtracting difference data between frames to correct for blurring due to motion), sensor or optical system induced artifacts (i.e. geometric aberrations), process induced artifacts (i.e. "worm" artifacts caused by error diffusion) or physical deterioration of a scanned object itself (i.e. dirt or dust on photos:graphic negatives).
