The Gordian Knot: Novel Methods for Digitally Identifying, Defining, and Separating Unique Rock Art Elements (2018)
In rock art research the stratigraphy of a rock art panel can offer great insight into the temporality of a panel, which can then inform many other aspects of analytical inquiry. Yet, making the necessary distinctions between elements is often difficult--as images fade and are worn by time, or the subjective nuances of the recorder. This paper explores novel means of identifying, defining, and separating unique rock art elements in digital space within different digital methodologies.
