The removal of lines is a very important pre-processing step before using ICR/OCR and recognizing characters from the acquired document.

Removes horizontal and vertical black lines from 1 bit images. After removing the lines, any intersecting characters or other image content will be reconstructed as accurately as possible.

C# example to remove lines from scanned image files,

string appPath = Path.GetDirectoryName(Application.ExecutablePath);
System.Type VeryPDFType = System.Type.GetTypeFromProgID("VeryPDF.PaperToolsCom");
VeryPDF.PaperToolsCom VeryPDFCom = (VeryPDF.PaperToolsCom)System.Activator.CreateInstance(VeryPDFType);

string appFolder = Path.GetDirectoryName(Application.ExecutablePath);
string strFolder = Directory.GetParent(appFolder).FullName;

string strReturn = "";
int nFileIndex = 0;
VeryPDFCom.EnableDebugLog(true);

string strInFile = strFolder + "\\sample\\test_table_ocr.tif";
string strOutFile = strFolder + "\\sample\\output\\_output_" + nFileIndex.ToString() + ".png";
string strCmd = "-$ XXXXXXXXXXXXXXXXXX -removelongline 0 -boxobjects \"" + strInFile + "\" \"" + strOutFile + "\"";
strReturn = strReturn + VeryPDFCom.PaperTools(strCmd);
