A Constant-Factor Approximation for Continuous Dynamic Time Warping in 2D
Kevin Buchin, Maike Buchin, Jan Erik Swiadek +1
Continuous Dynamic Time Warping (CDTW) is a robust similarity measure for polygonal curves that has recently found a variety of applications. Despite its practical use, not much is…
Compatible Triangulations of Simple Polygons
Peyman Afshani, Boris Aronov, Kevin Buchin +5
Let and be simple polygons with vertices each. We wish to compute triangulations of and that are combinatorially equivalent, if they exist. We consider two vers…
Algorithms and Lower Bounds for the Maximum Overlap of Two Polygons Under Translation
Mikkel Abrahamsen, Sujoy Bhore, Maike Buchin +4
A fundamental problem in shape matching and geometric similarity is computing the maximum area overlap between two polygons under translation. For general simple polygons, the best…
Fundamentals of Computing Continuous Dynamic Time Warping in 2D under Different Norms
Kevin Buchin, Maike Buchin, Jan Erik Swiadek +1
Continuous Dynamic Time Warping (CDTW) measures the similarity of polygonal curves robustly to outliers and to sampling rates, but the design and analysis of CDTW algorithms face m…
Property Testing of Curve Similarity
Peyman Afshani, Maike Buchin, Anne Driemel +2
We propose sublinear algorithms for probabilistic testing of the discrete and continuous Fréchet distance - a standard similarity measure for curves. We assume the algorithm is giv…
Faster Fréchet Distance under Transformations
Kevin Buchin, Maike Buchin, Zijin Huang +2
We study the problem of computing the Fréchet distance between two polygonal curves under transformations. First, we consider translations in the Euclidean plane. Given two curves…
