A sampling method for processing contours drawn with an uncertain stroke order and number
Kazuya Ose, Kazunori Iwata, Nobuo Suematsu · 2017
Although there are several effective methods for placing sample points on contours drawn with a certain stroke order and number, little attention has been paid to methods for placing sample points on contours with an uncertain stroke order and number. In this paper, we place sample points appropriately on such contours using an optimization method. The underlying idea is to take into account the degree in graph theory and edge length in geometry for the optimization. Using a dataset of line drawings, we confirm that our method, provides an appropriate placement of sample points in terms of shape retrieval.
