Kayla Makela, Tim Ophelders, Michelle Quigley +3
Tree ring widths are an important source of climatic and historical data, but measuring these widths typically requires extensive manual work. Computer vision techniques provide pr…
Between Shapes, Using the Hausdorff Distance
Marc van Kreveld, Tillmann Miltzow, Tim Ophelders +2
Given two shapes and in the plane with Hausdorff distance , is there a shape with Hausdorff distance to and from and ? The answer is always yes, and dep…
A family of metrics from the truncated smoothing of Reeb graphs
Erin Wolf Chambers, Elizabeth Munch, Tim Ophelders
In this paper, we introduce an extension of smoothing on Reeb graphs, which we call truncated smoothing; this in turn allows us to define a new family of metrics which generalize t…
