  • Method for retouching screened binary image data redigitized in pixels
    Publication number: 20020154831
    Abstract: Binary screen image data redigitized in pixels are retouched, specifically to eliminate local screen defects such as dust artifacts and scratch artifacts. Defective screen dots are selected and recorded for the purpose of detecting screen defects. Then, dust artifacts and scratch artifacts or the like are removed from contaminated image data. Furthermore, missing points in the screen are also filled up, and inhomogeneous image regions are corrected in part. The production of visible moire effects in the retouched image data is avoided by the replacement of only small areas.
