# Enable a Stroke Width Filter

All characters in a typical string have the same stroke width, and the OCRMax tool can be configured to disregard potential character features that do not match the typical stroke width of features in the rest of the image.

By default, the stroke width filter is enabled, which allows the OCRMax tool to correctly identify characters in images where there can be a defect such as an errant line or a scratch within a character or between two or more adjacent characters.

The UseStrokeWidthFilter property will enable or disable the filter.

Be aware that the tool will incorrectly remove whole characters or portions of characters if the stroke widths are inconsistent. Experiment with test images to discern whether this option should be enabled or disabled.
