Line 19: ==Theory== The theory of GVF was originally described ~~in.~~by Xu and Prince <ref name=":2" />. Let <math>\textstyle f(x,y)</math> be an edge map defined on the image ___domain. For uniformity of results, it is important to restrict the edge map intensities to lie between 0 and 1, and by convention <math>\textstyle f(x,y)</math> takes on larger values (close to 1) on the object edges. The gradient vector flow (GVF) field is given by the vector field <math>\textstyle \mathbf{v}(x,y) = [u(x,y),v(x,y)]</math> that minimizes the energy functional {{numBlk\|\| :<math display = "block">
