    DespeckleMode Property
    In This Topic
    Gets or sets a value indicating whether the adaptive noise removal algorithm is to be activated during image pre-processing, auto-zoning or recognition.

    Property Value

    Boolean value.
    Remarks

    This property specifies the image despeckle mode setting, i.e. whether the adaptive noise removal algorithm is to be activated during image pre-processing, auto-zoning or recognition. The noise removal algorithm runs only on bitonal images with a resolution of 280 DPI or higher.

    Note: When despeckle runs as part of the preprocessing (rather than called explicitly), it works on an internal secondary image, so its result is not available for exporting back to the application. Use Despeckle method for explicit despeckling. See The Recognition Process section for explanation of the "secondary image" term.

    This setting might influence the accuracy of the recognition.
