An Objective Evaluation Methodology for Document Image Binarization Techniques
TL;DR: An objective evaluation methodology that aims to reduce the human involvement in the ground truth construction and consecutive testing and a benchmarking of the six most promising state-of-the-art binarization algorithms based on the proposed methodology is presented.
Journal ArticleDOI
Combining multispectral data of differing spatial resolution
TL;DR: An improvement to an existing band correlation method is described for merging high spatial resolution imagery with data from additional lower spatial resolution bands and a figure of merit quantifies the improvement over pixel replication of the lower resolution imagery.

Automatic thresholding of gray-level using multistage approach
Sue Wu,Adnan Amin +1 more
TL;DR: A multistage approach is presented for thresholding document images, along with its application, which automatically customizes the thresholding of regions that have specific and consistent characteristics but are different to other regions in the image.
