Figure 5
Line profiles along the dashed lines highlighted in the yz views found in the 2nd row in Fig. 4[link]. The filtered profiles were shifted on the ordinate axis for better visibility of the periodic fine structure of the butterfly wing. While the median filter introduces a phase shift to the profile, the NLM filter and ML filter maintain the phase. The amplitude of the signal is best preserved with the ML filter.
