چکیده |
This paper presents an efficient algorithm for
adaptive binarization of degraded document images.
Document binarization algorithms suffer from poor
and variable contrast in document images. We propose
a contrast independent binarization algorithm that
does not require any parameter setting by user.
Therefore, it can handle various types of degraded
document images. The proposed algorithm involves
two consecutive stages. At the first stage, independent
of contrast between foreground and background, some
parts of each character are extracted and in the second
stage, the gray level of foreground and background are
locally estimated. For each pixel, the average of
estimated foreground and background gray levels is
defined as threshold. After extensive experiments, the
proposed binarization algorithm demonstrate superior
performance against four well-know binarization
algorithms on a set of degraded document images
captured with camera. |
