The choice of the best binarization algorithm is very critical for any document image processing system, since it is one of the first tasks and any mistake it performs will be car...
Abstract--We attempt to evaluate the efficacy of six unsupervised evaluation method to tune Sauvola's threshold in optical character recognition (OCR) applications. We propose...
In this paper, we present a binarization technique specifically designed for historical document images. Existing methods for this problem focus on either finding a good global th...
Abstract--This paper extends the transition method for binarization based on transition pixels, a generalization of edge pixels. This method originally computes transition threshol...
—A vast number of historical and badly degraded document images can be found in libraries, public, and national archives. Due to the complex nature of different artifacts, such p...
