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 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: In this paper, we first extend the Wirtinger derivative which is defined for complex functions to hyperbolic functions, and derive the hyperbolic gradient operator yielding the steepest ...

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 ...
