Hausdorff distance - Wikipedia

WebTools. In mathematics, the Hausdorff distance, or Hausdorff metric, also called Pompeiu–Hausdorff distance, [1] [2] measures how far two subsets of a metric space are from each other. It turns the set of non-empty compact subsets of a metric space into a metric space in its own right. It is named after Felix Hausdorff and Dimitrie Pompeiu .

It is named after Felix Hausdorff … See more Let X and Y be two non-empty subsets of a metric space $${\displaystyle (M,d)}$$. We define their Hausdorff distance $${\displaystyle d_{\mathrm {H} }(X,Y)}$$ by See more • In general, $${\displaystyle d_{\mathrm {H} }(X,Y)}$$ may be infinite. If both X and Y are bounded, then $${\displaystyle d_{\mathrm {H} }(X,Y)}$$ is guaranteed to be finite. See more In computer vision, the Hausdorff distance can be used to find a given template in an arbitrary target image. The template and image are often pre-processed via an edge detector giving a binary image. Next, each 1 (activated) point in the binary image of the template is … See more • Wijsman convergence • Kuratowski convergence • Hemicontinuity See more The definition of the Hausdorff distance can be derived by a series of natural extensions of the distance function $${\displaystyle d(x,y)}$$ in the underlying metric space M, as follows: • Define a distance function between any point x of M and … See more A measure for the dissimilarity of two shapes is given by Hausdorff distance up to isometry, denoted DH. Namely, let X and Y be two compact figures in a metric space M (usually a Euclidean space); then DH(X,Y) is the infimum of dH(I(X),Y) along all See more • Hausdorff distance between convex polygons. • Using MeshLab to measure difference between two surfaces A short tutorial on how to … See more o\u0027grady realty highland beach
