Comments on "Nonparametric segmentation of curves into various representations" [with reply]

The author points out the existence of a theoretical difficulty that underlies the curve segmentation problem studied in the work of Rosin and West (ibid., vol.17, no.12, p.1140-53, 1995) and present a possible solution to it. The problem arises because curves are segmented into low- and high-order features, and the former are a subset of the latter. In reply, Rosin and West discuss the advantages and disadvantages of two approaches to model selection: their original heuristic sequential method, and the information theoretic method suggested by Kanatani and others.
