Signed euclidean distance transform

If Ω is a subset of the Euclidean space R with piecewise smooth boundary, then the signed distance function is differentiable almost everywhere, and its gradient satisfies the eikonal equation $${\displaystyle \nabla f =1.}$$ If the boundary of Ω is C for k ≥ 2 (see Differentiability classes) then d is C on points … See more In mathematics and its applications, the signed distance function (or oriented distance function) is the orthogonal distance of a given point x to the boundary of a set Ω in a metric space, with the sign determined by … See more Algorithms for calculating the signed distance function include the efficient fast marching method, fast sweeping method and the more general See more • Distance function • Level-set method • Eikonal equation • Parallel (aka offset) curve • Signed arc length See more If Ω is a subset of a metric space X with metric d, then the signed distance function f is defined by where See more Signed distance functions are applied, for example, in real-time rendering, for instance the method of SDF ray marching, and computer vision.

WebMentioning: 39 - The signed Euclidean distance transform and its applications - Ye, Q.-Z. A distance transform, also known as distance map or distance field, is a derived representation of a digital image. The choice of the term depends on the point of view on the object in question: whether the initial image is transformed into another representation, or it is simply endowed with an additional map or field. Distance fields can also be signed, in the case where it is important to distinguish whether the p…
