Region-based document image denoising

TL;DR: Test result on UNLV with 11176 samples shows that the average recognition rate rises from 94.44% to 94.85% by using region based image de-noising, which proves that the deficiency of traditional method can be overcome.

Survey over image thresholding techniques and quantitative performance evaluation

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.
