Abstract(in English) | General Two-Dimensional (2D) code decoders read 2D codes without any distortion or with uniform distortion, and it is hard for the decoders to read 2D codes involving partial, non-linear distortion. The authors have proposed a 2D code involving colored auxiliary lines for the correction of distortion and recognition of occlusion regions. However, the decoder sometimes fails to read modules around an occlusion boundary. Therefore, this paper attempts to improve a decode method for the 2D code involving the colored auxiliary lines. The improved decoder revises line recognition result by estimating reliability of line recognition and iterated dynamic programming matching. Experimental results show that the proposed method decodes the 2D code involving partial, nonlinear distortion with higher accuracy than the previous decoder. |
