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 ...

exp 4a 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 change in pixel ...

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, ...

Abstract: This paper addresses explainability of the operator-regularization approach under the use of monotone Lipschitz-gradient (MoL-Grad) denoiser — an operator that can be expressed as the ...

Medical image segmentation is a crucial task in computer-aided diagnosis. Although convolutional neural networks (CNNs) have made significant progress in the field of medical image segmentation, the ...
