“…The development of digital techniques, far from having cast aside this approach, has streamlined the drawing process (Kampel and Sablatnig, 2003;Karasik and Smilansky, 2008), provided advanced calculation tools and eased the three-dimensional representation. Thus, for example, profiles have been in use for multiple purposes, from the straightforward computation of the volume of the vessel (Zapassky et al, 2006;Sánchez and Cerdeño, 2014) to more complex applications including the classification of pottery items and their description by means of a series of mathematical parameters. Afterwards, such parameters can be used for establishing similarities between pieces, clustering and searching (Sablatnig and Menard, 1997;Liu and Razdan, 2004;Koutsoudis et al, 2010;Martínez-Carrillo et al, 2010a;Karasik and Smilansky, 2011;Wilczek et al, 2014;Lucena et al, 2016).…”
