Description: This paper proposes a novel document image
binarization approach based on stroke neighborhood
enhancement. First, foreground pixels are initially
labeled. Then, the strokes are enhanced based on their
neighborhood information which include gradient
information and foreground-background pixel distances
of foreground pixels and their neighboring background
pixels. At last, the enhanced image is finally
binarized. This approach can provide good result for
those document images suffering from lighting variance,
low resolution and blurring.
