Deep learning‐based methods for detecting defects in cast iron parts and surfaces

open access: yesIET Image Processing, Volume 18, Issue 1, Page 47-58, 10 January 2024.
First, this article used multiple data augmentation methods to alleviate the problem of small sample size in casting datasets. Second, attention mechanism was introduced. Finally, a novel feature fusion layer structure was adopted to improve the original network model.

mBCCf: Multilevel Breast Cancer Classification Framework Using Radiomic Features

open access: yesInternational Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.
Breast cancer characterization remains a significant and challenging issue in contemporary medicine. Accurately distinguishing between malignant and benign breast lesions is crucial for effective diagnosis and treatment. The anatomical structure of malignant breast ultrasound images is more chaotic than that of benign images due to disease pathologies.

Sparse Regularization Based on Orthogonal Tensor Dictionary Learning for Inverse Problems

open access: yesMathematical Problems in Engineering, Volume 2024, Issue 1, 2024.
In seismic data processing, data recovery including reconstruction of the missing trace and removal of noise from the recorded data are the key steps in improving the signal‐to‐noise ratio (SNR). The reconstruction of seismic data and removal of noise becomes a sparse optimization problem that can be solved by using sparse regularization.

A unified comparative framework for multiscale geometric transforms in SAR and multispectral satellite image analysis

open access: yesFrontiers in Remote Sensing
Satellite image analysis is essential for remote sensing analysis. Two types of data are captured via satellite: Synthetic Aperture Radar (SAR) imagery (which has structure) and multispectral imagery (which contains spectral information), so ...

Radon transform inversion using the shearlet representation

open access: yes, 2010
The inversion of the Radon transform is a classical ill-posed inverse problem where some method of regularization must be applied in order to accurately recover the objects of interest from the observable data. A well-known consequence of the traditional

Blind Image Watermark Detection Algorithm Based on Discrete Shearlet Transform Using Statistical Decision Theory [PDF]

open access: yes, 2018
Blind watermarking targets the challenging recovery of the watermark when the host is not available during the detection stage. This paper proposes Discrete Shearlet Transform (DST) as a new embedding domain for blind image watermarking.
