|
The initial stage of the document image is pre-processing. When we see historical document it will be
degraded and it need to be preserved. Here in this paper we are considering the aged historical document of
agreement copy and we are performing binarization to the document. Many methods has been proposed for
binarization but there no perfect method for each every type of the document. So we propose a novel method
by using both local thresholding and global thresholding and check their accuracy of the each method. We use
Otsu, Niblack, sauvola, wolf methods and added morphological operation like dilation and erosion which gives
extra clarity to the document. The dataset we have collect is from both Kannada and Malayalam. Promising
result was seen with the accuracy of 87.03% which is better than other proposed methods for the agreement
copy.
