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.

Automatic eye blink artifact removal for EEG based on a sparse coding technique for assessing major mental disorders [PDF]
Journal of Integrative Neuroscience, 2019 In the electroencephalogram recorded data are often confounded with artifacts, especially in the case of eye blinks. Different methods for artifact detection and removal are discussed in the literature, including automatic detection and removal. Here, an

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 ...
