Pansharpening with the Multidirection Tree Ridgelet Dictionary

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022
In this work, we propose a novel pansharpening method based on the multidirection tree ridgelet dictionary. A pansharpened image has a wide‐ranging application area, such as object detection, image segmentation, feature extraction, and so on. Remote sensing (RS) imagery contains more abundant information on surface features.

Robust Watermarking Algorithm against the Geometric Attacks based on Non‐Subsampled Shearlet Transform and Harris‐Laplace Detector

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

A Comparative Study among Handwritten Signature Verification Methods Using Machine Learning Techniques

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.

Scale space Radon transform

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 ...

A novel hybrid downsampling and optimized random forest approach for islanding detection and non‐islanding power quality events classification in distributed generation integrated system

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 ...
