We investigate clustering of 2D contours which represent cross-sections of rotationally symmetric objects. We propose modifications of the existing representations of digitized 2D contours and similarity measures. In particular, we represent each of the investigated objects as a single number and two functions and we use the DTW distance to measure their similarity. We apply our method to clustering of pottery fragments.
The person ordering the research was Mr. Andrzej Cichy of the Faculty of Wood Technology at the Warsaw University of Life Sciences. The painting was made available from his private collection. The aim of the research conducted by SMARTTECH was to study the impact of changes in humidity on the deformation of a wooden panel painting support.
