Samples of the reconstructed closed boundaries (from the MPEG-7database) at CR = 3% and 7%. The normalized L1 distance is also presented.As shown, Seg-FD + the proposed Fourier descriptor scheme outperforms theother methods on both the reconstruction quality and the L1 error.(b)Fig. 19. Samples of the reconstructed Chinese characters at CR = 5% and 8%.The normalized L1 distance is also presented. As shown, Seg-FD + theproposed Fourier descriptor scheme outperforms the other methods on boththe reconstruction quality and the L1 error.
