Faxed documents often contain annoying horizontal lines due to communication noise on the telephone line. Scanned document in some cases, also have horizontal or vertical lines due to the banding or folding of papers.By utilizing LinesHelper these lines can automatically be removed.


The document structure analysis and character recognition are usually done in several phases:

  • scanning
  • thresholding
  • skew detection and correction
  • despeckle or speckle removal
  • line removal
  • border removal
  • detection of preprinted elements (like boxes)
  • page orientation detection and correction
  • layout analysis
  • classification
  • character recognition

Each step must be completed well enough for the performance of the sequence and result to be successful. Steps that follow the line removal are inefficient if the correction fails.

LinesHelper finds and removes horizontal and vertical lines and repairs overlapping text and graphics on binary images. The line removal filter can also be configured to reconstruct horizontal and vertical lines, redrawing them straight with smooth edges. LinesHelper expects as input a monochrome image.
