摘要：In this paper, we present two comparisons in isolated handwritten Roman numerals recognition, in fact thefirst comparison is between zoning methods exploited in features extraction which are the square zones or thetriangular zones used in extraction characteristic; in contrast the second comparison is performed in order todeduce what is the most powerful between the type of writing used with a pen or marker. For this purpose wehave used for pre-processing each numeral image the median filter, the thresholding, the normalization, thethinning, the centering and the skeletonization techniques. Furthermore, the experiments results that we haveobtained demonstrates really that the most powerful method is that the zoning with 9 square then with 8triangular. This work has achieved approximately 85% of success rate for Roman numerals databaseidentification.
