Collected scans were post-processed in Blender (v 3.3.1), to remove irrelevant data such as the participants torso, to remove miscellaneous/broken geometry, and scale meshes. Two distinct scaling methods were used, splitting the dataset into two halves. These were the Naive set, in which the meshes were scaled according solely to the reference geometry captured in the scan, and the Optimal set, in which the meshes were scaled according to the Artec criterion scans, resulting in a more accurate scaling operation. Once complete, the scans were compiled and aligned in Artec Studio 12, and split into ten sections along their lengths. The data collected from these sections included perimeter, cross-sectional area, and total volume. A separate measurement operation was performed to gather RMSE data, for which a search distance of 15 mm was used.
