Edges are significant local changes of intensity in a digital image. An edge can be defined as a set of connected pixels that forms a boundary between two disjoint regions. There are three types of ...

Abstract: Estimating gradients of color images is important to many color image processing tasks. However, the research on color image gradients is limited. In this paper, a novel method of estimating ...

EXP 4-a - Gradient Operator = The gradient operator in image processing is used to detect edges by highlighting areas where the intensity of an image changes rapidly. The operator computes the rate of ...

Abstract: A new gradient operator was derived in recent studies of topological structures and shape transitions in biomembranes. Because this operator has widespread potential uses in mechanics, ...

Quantum optimization, a key application of quantum computing, has traditionally been stymied by the linearly increasing complexity of gradient calculations with an increasing number of parameters.

We cast policy gradient methods as the repeated application of two operators: a policy improvement operator $\mathcal{I}$, which maps any policy $\pi$ to a better one $\mathcal{I}\pi$, and a ...
