Fig. 3.

The color histograms of four objects taken from sixteenth century manuscripts. From left to right the red, green and blue channels are presented. Each channel has been independently aligned by DTW. top The two examples from family crest of Lucas Fugger have radically different warpings in each of the three color channels, perhaps reflecting the fact that the book was created over a 4 year period. bottom In contrast, the two butterfly examples have essentially identical alignments (Albertus 1734) (Color figure online)
