In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held...

The topological derivative is, conceptually, a derivative of a shape functional with respect to infinitesimal changes in its topology, such as adding...

Mathematically, an image gradient represents the derivative of an image, so the goal of gradient domain processing is to construct a new image by integrating...
