Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 With the rapid spread of network information, the information maintenance has become the focus of information security on networks. Digital watermarking is one of the effective methods to protect information security, achieve anticounterfeiting traceability, and protect copyright, and it is an important branch of information hiding technology. However,

Clifford‐Valued Shearlet Transforms on Cl(P,Q)‐Algebras
Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022 The shearlet transform is a promising and powerful time‐frequency tool for analyzing nonstationary signals. In this article, we introduce a novel integral transform coined as the Clifford‐valued shearlet transform on Cl(p,q) algebras which is designed to represent Clifford‐valued signals at different scales, locations, and orientations. We investigated

Scientific Programming, Volume 2022, Issue 1, 2022., 2022 Nowadays, the verification of handwritten signatures has become an effective research field in computer vision as well as machine learning. Signature verification is naturally formulated as a machine‐learning task. This task is performed by determining if the signature is genuine or forged.

IET Image Processing, Volume 15, Issue 9, Page 2097-2111, July 2021., 2021 Abstract An extension of Radon transform by using a measure function capturing the user need is proposed. The new transform, called scale space Radon transform, is devoted to the case where the embedded shape in the image is not filiform. A case study is brought on a straight line and an ellipse where the SSRT behaviour in the scale space and in the ...

MULTISPECTRAL IMAGE FUSION USING SLANTLET-BASED RIDGELET TRANSFORM
Journal of Engineering, 2007 This paper introduces a new method in the multispectral image fusion based on ridgelet transform which represents edges better than wavelets. Since edges play a fundamental rule in image understanding, one good way to enhance spatial resolution is to ...

IET Renewable Power Generation, Volume 15, Issue 8, Page 1662-1677, 8 June 2021., 2021 Abstract The quality of power in modern‐day power system is polluted with increased penetration of converter‐based distributed generations such as wind farm, solar PV system. In such scenarios detection of islanding and power quality disturbances as well as the removal of these from the system is quite crucial for equipment and maintenance personnel ...

3-D Discrete Analytical Ridgelet Transform [PDF]
IEEE Transactions on Image Processing, 2006 In this paper, we propose an implementation of the 3-D Ridgelet transform: the 3-D discrete analytical Ridgelet transform (3-D DART). This transform uses the Fourier strategy for the computation of the associated 3-D discrete Radon transform. The innovative step is the definition of a discrete 3-D transform with the discrete analytical geometry theory ...
