(a) An illustration of the common line between two patterns of similar-shaped objects but with different orientations. (b) The distribution of 1000 averages in the 3D CLPCA space. Different colours are manually divided groups from the first two components: contaminants (blue), cubes (red), transition (yellow) and spheres (green). Typical patterns for averages in each group are also shown on a logarithmic scale.
