Recognizing decorated characters using conventional Optical Character Recognition (OCR) requires that the structure of the decorated characters be extracted. The method that Omachi et al. proposed to do this could not extract characters including both thin and thick lines. To improve the performance of Omachi’s approach, we proposed using graph spectral decomposition, demonstrating our previous proposal’s applicability to wider range of decorated characters. Here we propose a new criterion for selecting structure extraction components in the graph spectral decomposition framework, demonstrating the feasibility of the criterion through experimental results.
