A Multistage Binarization Technique for the Degraded Document Images

Abstract

Efficient image binarization technique is critical for achieving high quality in the document image analysis pipeline. The binarization process is a challenging and a very difficult task because these document images may be degraded where they may be suffering from aging, leaked ink, bleeding through, stains, smudge, spots, image contrast variation, non-uniform illumination, heat damage, etc. Conventional binarization techniques do not take all these degradations into account
