| Zusammenfassung: | A method for use in a recursive spatial filter which interchanges the value of a control pixel with that of the value of a predetermined one of the surrounding pixels in a pixel mask when a specific image pattern occurs in the digital image. The use of such a method eliminates certain highly visible grain patterns from the halftoned digital image while preserving the average gray level. |
