Despeckling an Image

When you select a single job for despeckling, the image is displayed in the preview area of the dialog. If you select multiple jobs, the preview pane and navigation buttons are not displayed. You can despeckle images with the MrSID Generation 4, MrSID Generation 3, or JPEG 2000 output format.

  1. Add a source image or mosaic to the Job List.

  2. Click the Despeckle button on the toolbar.

    The Despeckle Options dialog box appears.

  3. Select the Despeckle Output check box.

  4. Optionally, enter threshold and point spacing values by typing them in the edit fields or using the slider controls (see below for information about these values). Note: The sliders only move within the recommended range (1-127 for threshold and 6-12 for point spacing), but you may enter any integer greater than zero in the fields.
  5. Optionally, to preview the effects of the threshold at different settings select the View Threshold check box and then move the Threshold slider. Black areas are pixels whose values fall below the threshold and will be used to determine the despeckling collar of the image.
  6. Click OK.
