Figure 3. The Morphological Similarity of Tensors in the Presence of Varying Noise Levels.

Figure 3

Similarities were computed using our measure for (a) varying eigenvalues and (b) varying angles of rotation. The eigenvectors of the unperturbed tensor were aligned along the coordinate axes with eigenvalues 5, 10, and 20. The width of the bell-shaped distribution of similarity values increased with increasing noise levels. The graphs labeled var2, var4, var6, var8, var10, and var12 are similarity values for noise variance equal to 2, 4, 6, 8, 10, and 12, respectively.
