QFPJFMs: Quaternion Fractional-Order Pseudo-Jacobi–Fourier Moments
As one promising solution, zero-watermarking approaches have been proposed to enhance the image visual quality and applied to protect the intellectual property rights of the medical images, remote sensing images and military images. The moments ...
Mathematical Properties of Pyramid-Transform-Based Resolution Conversion and Its Applications
In this paper, we aim to clarify the statistical and geometric properties of linear resolution conversion for registration between different resolutions observed using the same modality. The pyramid transform is achieved by smoothing and ...
Geometry Parameter Estimation for Sparse X-Ray Log Imaging
We consider geometry parameter estimation in industrial sawmill fan-beam X-ray tomography. In such industrial settings, scanners do not always allow identification of the location of the source–detector pair, which creates the issue of unknown ...

Electrical impedance tomography (EIT) is a non-ionizing imaging modality suitable for bedside pulmonary imaging. Currently, lung imaging with EIT in the ICU is tomographic due to the need for real-time images. However, linearized reconstruction ...
