چکیده |
In this paper, we present a novel hybrid algorithm
for binarization of badly illuminated document images.
This algorithm locally enhances the document image
and makes the gray levels of text and background
pixels separable. Afterward a simple global
binarization algorithm binarizes the enhanced image.
The enhancement process is a novel method that uses a
separate transformation function to map the gray level
of each pixel into a new domain. For each pixel, the
transformation function is determined using its
neighboring pixels gray level. The proposed
binarization algorithm is robust for wide variety of
degraded document images. Evaluation over a set of
degraded document images illustrates the effectiveness
of our proposed binarization algorithm. |
