| Abstract(in English) | This paper describes enhancements of the ruled line extraction method using threshold correction and linearity evaluation. Recent form recognition applications are required to achieve high accuracy even with various styles of form images being much degraded. To meet the high-level demand, we have developed several methods which can suppress mis-recognition cases caused by failed or over extracted ruled lines. The proposed methods include correcting binarization thresholds and evaluating linearity of ruled lines. These methods are considered as an implementation of the ruled line model described briefly in the beginning of this paper. Details of our methods, performance evaluation results and discussions are presented. |
