Adjustments in this dialog help distinguish clutter from character fragments.
Set the Min. Fragment Size to define the minimum size of a connected structure that is not regarded as clutter either by entering a value in the text field or using the slider on the right. This value can be reset to the default value by clicking the button on the right side of the slider.
Symbol Fragmentation also contains two checkboxes that should be deactivated if the settings are not helpful for a special application. By default, fragments are connected to form characters. Border fragments, fragments extending from outside into the region of interest, are eliminated.
