## weight function

[′wāt ‚fəŋk·shən]

Two real valued functions ƒ and g are orthogonal relative to a weight function σ on an interval if the integral over the interval of ƒ· g ·σ vanishes.
A function defined on the edges of a network or the arcs of a directed network, whose value at each edge or arc is the unique nonnegative integer assigned to that edge or arc.
A function defined on the vertices of a generalized s-t network, whose value at each vertex is a nonnegative integer.

In order to do this, there have been implemented two voting methods: Region Based (which is similar to the Region-Growing algorithm) and Weights Based (which uses a weighted sum scheme, followed by a re-clustering algorithm).
