Adaptive degraded document image binarization

Web•Gatos - "Adaptive degraded document image binarization", 2005. (Partial) •NICK - "Comparison of Niblack inspired Binarization methods for ancient documents", 2009. WebThis paper presents a new adaptive approach for the binarization and enhancement of degraded documents. 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.

Novel Adaptive Binarization Method for Degraded Document Images

WebImage binarization is the process of representing an image pixel in binary format by assigning a value to the pixel as either 0 or 1. Before conversion to binary, the image can be in either gray-scale having pixel value between 0 to 255 or color, i.e., a pixel having value between 0 to 255 for each of the red, green, blue (RGB) channels separately.
