The segmentation step of retinal blood vessel helps to diagnosis the diseases including
diabetic retinopathy, glaucoma, etc. The automatic image segmentation process helps …

Wear characterization with ferrography is an effective off-line method for monitoring a
machine's wear condition. The new challenge of real-time wear reporting appeared in …

This article extends the Radon transform, a classical image-processing tool for fast
tomography and denoising, to the quantum computing platform. A new kind of periodic …

This paper discusses the decomposition of the image by direction images, which is based
on the concept of the tensor representation and its advanced form, the paired …

The discrete Fourier transform (DFT) underpins the solution to many inverse problems
commonly possessing missing or unmeasured frequency information. This incomplete …

In this letter, we demonstrate how characteristics of a permutation of the Hadamard
transform (HT), known as the binary discrete Hartley transform (BDHT), can be leveraged to …

This study presents an integer‐only algorithm to exactly recover an image from its discrete
projected views that can be computed with the same computational complexity as the fast …

The discrete Fourier slice theorem is an important tool for signal processing, especially in
the context of the exact reconstruction of an image from its projected views. This paper …

This paper presents a discrete generalized multi-directional Radon transform (GMDRT) 1
and its exact inversion algorithm. GMDRT is an extension of the classical Radon transform. It …

This paper introduces a sparse projection matrix composed of discrete (digital) periodic lines
that create a pseudo-random (p. frac) sampling scheme. Our approach enables random …
