TLDR
The proposed method does not require any parameter tuning by the user and can deal with degradations which occur due to shadows, non-uniform illumination, low contrast, large signal-dependent noise, smear and strain.About:

Text extraction from degraded document images
TL;DR: A robust segmentation method for text extraction from the historical document images is presented that employs significantly the local and spatial correlation and coherence on both the image and between the stroke parts, and therefore is very robust with respect to the degradation.

History Document Image Background Noise and Removal Methods
TL;DR: A hybrid binarization approach for improving the quality of old documents is proposed using a combination of global and local thresholding and noises that might appear in scanned document images are reviewed.

Survey over image thresholding techniques and quantitative performance evaluation
Mehmet Sezgin,Bulent Sankur +1 more
TL;DR: 40 selected thresholding methods from various categories are compared in the context of nondestructive testing applications as well as for document images, and the thresholding algorithms that perform uniformly better over nonde- structive testing and document image applications are identified.
