N04_Area_Normalized_Rim_Overlay

We center each polygon at its area centroid, rotate it to the principal axis of 256 equally spaced boundary samples, and divide both coordinates by the square root of polygon area. The resulting profiles each have unit area. We do not treat their vertices as homologous landmarks or use this display as a taxonomic test.
