Detailing a Quantitative Method for Assessing Algorithms to Remove Back-to-Front Interference in Documents

Documents written on both sides on translucent paper make visible the ink from one side on the other. This artefact is called "back-to-front interference", "bleeding" or "show-through". The direct binarization of documents with such interference yields unreadable documents. The literature presents several algorithms for suitably removing such artefact. This paper presents a quantitative method to assess algorithms to remove back-to-front interference.
