Binarization of Ancient Document Images based on Multipeak Histogram Assumption

Fitri Arnia, Khairul Munadi
2017 TELKOMNIKA (Telecommunication Computing Electronics and Control)  
In our simulations we used a set of Jawi ancient document images with natural noises. This set is composed of 24 document tiles containing two noise types: show-through and uneven background.  ...  In ancient documents, that are commonly noisy, binarization becomes more difficult. The noise can reduce binarization performance, and thus the OCR rate.  ...  Conclusion In this paper, we proposed a novel binarization method for ancient noisy document images, based on the assumption that histograms of the document images consist of multipeaks.  ...
