A multi-directional gradient with bi-geometric calculus to detect contours in images with multiplicative noise
(2018)
In this paper a new operator is presented for the detection of contours in images with multiplicative noise, by using the operations introduced in the bi-geometric calculus, since recent results in the literature show that ...
Contour detection in images with speckle by using the bi-geometric structure
(2019)
The speckle produces severe degradations in digital images, which could be introduced by technological devices during the acquisition, capture or transmission of the images. This perturbation affects, for instance, medical ...
Multiplicative local binary patterns (MuLBP)
(2019)
Speckle is a multiplicative noise that greatly deteriorates images. In this paper a model of Local Binary Patterns (LBP) adapted to images with speckle (MuLBP) is proposed. The multiplicative model is constructed by ...
