HoughLevel

Specifies the available accuracy levels for advanced line detection using the Hough transform in Line Detection.

Remarks

The HoughLevel enumeration controls the use and precision of advanced line detection based on the Hough transform. When enabled, the Hough transform is used to detect faint, skewed, or non-axis-aligned lines that may not be found by standard morphological methods. Higher accuracy levels increase the sensitivity and precision of line detection, but may also increase processing time.

Use advanced line detection for documents with faint, broken, or slightly skewed lines, or when standard detection misses important features. Choose the lowest level that provides reliable results for your document set to balance accuracy and performance.

• 'Off': Disables advanced line detection; only standard methods are used.
• 'Low', 'Medium', 'High': Enable the Hough transform with increasing accuracy and computational cost.

Review diagnostic images to assess the effect of each level and tune for your specific needs.
