Rajan Goyal, Amandeep Kaur · 2011
Historical document are very important for the human history. There is a huge collection of punjabi historical documents that have invaluable knowledge about the history, culture and religion of punjab. These document have deteriorated due to age and lack of preservation facilities. These documents can be preserved by using binarization techniques. Binarization techniques can distinguish text from background. We perform binarization by using many techniques but all these techniques are based on basic techniques[niblack, kittlemet, otsu methods]. We analysis the result of these method by applying them on different images, conclude which method is efficient for which type of image and further analyzing the combination of the methods, that are much suitable for each type of image.
