In vector calculus, the gradient of a scalar field is a vector field which points in the direction of the greatest rate of increase of the scalar field, and whose magnitude is the greatest rate of c...

The new snake is based on a new type of external force field, called gradient vector flow, or GVF. This field is computed as a spatial diffusion of the gradient of an edge map derived from the image. This computation causes diffuse forces to exist far from the object, and crisp force vectors near the edges.

Geometric Description of the Gradient Vector ... The gradient vector <8x,2y> is plotted at the 3 points (sqrt(1.25),0), (1,1), (0,sqrt(5)). As the plot shows, the gradient vector at (x,y) is normal to the level curve through (x,y). As we will see below, the gradient vector points in the direction of greatest rate of...

Vector calculus identities - Wikipedia, the free encyclopedia
The following identities are important in vector calculus: This section explicitly lists what some symbols mean for clarity. For a vector field \mathbf{v} , divergence is generally written as \op...

The *gradient* is a fancy word for derivative, or the rate of change of a function. It's a vector (a direction to move) that * Points in the direction of ... Unless I’m mistaken, the gradient vector always points in the direction of greatest increase (greatest decrease would be in the opposite direction).

The Gradient Vector ... Offers an intuition about the gradient vector. Some of the graphics were made more attractive by code borrowed from the Calculus & Mathematica program in the Department of Mathematics at the University of Illinois at Urbana-Champaign.

Gradient vector fields are also called conservative vector fields, because the work done by a particle moving in a closed loop against a gradient vector field is always 0. The curl of a gradient vector field is the zero vector;
