Metal artifacts, caused by high-density metallic implants in computed tomography (CT) imaging, severely degrade image quality, complicating diagnosis and treatment planning. While existing deep ...

Abstract: Digital signal and image processing using reduced biquaternions (RBs) are introduced in this paper. RBs are an extension of the complex numbers, following the doubling procedure. Two useful ...

Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a fundamentally new type of optical spectrometer that delivers ...

At the same time, we need to think carefully about how to use them and how to prevent their misuse. I oppose recent suggestions that we simply ban their development, but I support and participate in ...

Abstract: Deep convolutional neural networks (DCNNs) have recently emerged as a powerful tool to deliver breakthrough performances in various image analysis and processing applications. However, DCNNs ...

Steps of the proof 1. Calculation of Fourier coefficients $$ { \hat {\Delta}_a (n) }$$ and confirmation of the sign First, to confirm the hint " $$ { \hat {\Delta}_a (n) \ge 0 }$$ ", we calculate the ...
