Abstract

Text “underlining” is a practice of many interested readers, but it may be seen as a noise inserted by the user that damages the physical integrity of a document. This paper presents two different algorithms for underline removal. The first one addresses the case of monochromatic document images. The second algorithm is applied to remove the underline noise in recent and aged documents written on a blank sheet of white paper. Underline information is also used to automatically generate summaries of documents.
