| Summary: | The old documents in Jawi script are being used
widely for references. The hard copies of those scripts will
deteriorate as time passes. Most of the previous works on Jawi
documents focused on the character recognition and the accuracy
of the algorithm was very much affected by noise. An effective
preprocessing method is required to binarize degraded Jawi
document. In this paper, a new technique to threshold degraded
Jawi document is proposed. The results of the new algorithm
were also evaluated and compared with several algorithms. The
quality of the thresholding methods was assessed using visual
inspection and mathematical evaluation. The results show that
the new technique has outclassed other binarization algorithms. |
