7 Binarization and Color Separation Binarization dialog box Binarization of color images is performed using the Binarization dialog box. To open the Binarization dialog box Choose Binarization from the rImage menu. - or Click the button on the WiseImage toolbar. The Binarization dialog with the Range tab open The controls and buttons described below are the same for the Threshold and Ranges tabs of the Binarization dialog box. Preview window This window dynamically displays the binarization results for part of an image. Note that if you choose a color sample in the image with an eyedropper, the preview window marks the position of the selected pixel with a cross. If color selection is performed in the preview area, then its position is shown with a color frame (red by default) on the image. * For more information on preview window see "Preview Window " on page 17. Noise Reduction This slide sets the sensitivity of the binarization algorithm to small details in the image. If maximum level of noise reduction is set, then the quantity of raster noise and holes in the obtained monochrome raster objects is reduced. However, the high level of noise reduction decreases the binarization quality of small and thin details, such as texts, thin lines, etc, since small details can be taken for noise. If you apply a low level of noise reduction, then the quality of small detail binarization improves, but the quantity of raster noise increases. 91
