Noise Filter | Occasionally small dots or specks appear in the background of a |
| scanned image. These specks increase file compression size and |
| usually contain no image information. Using the Noise Filter on |
| documents containing very fine detail (e.g., the dot on an "i" in |
| type) may cause information to be lost. It is recommended that you do |
| not use the Noise Filter when scanning documents with text smaller than |
| |
| Noise Filter can be used with binary images only and is Front/Rear and |
| dual stream independent. Choose None, Lone Pixel or Majority Rule. |
| • Lone Pixel reduces random noise on binary images by converting a |
| single black pixel surrounded by white to white or by converting a |
| single white pixel surrounded by black to black. |
| • Majority Rule sets the central pixel value in a matrix according to |
| the majority of white or black pixels in a matrix. |
