This repository provides a Python implementation of the Pseudo-Polar Fourier Transform (PPFT) in both 2D (PPFT2D) and 3D (PPFT3D), based on the methods presented in the following papers: ...

From a pinch of cumin to rosemary and sage, certain ingredients are getting attention from researchers and doctors for more than just their flavor. This year, new studies and expert opinion have put ...

Introduction: Brain-computer interfaces (BCIs) leverage EEG signal processing to enable human-machine communication and have broad application potential. However, existing deep learning-based BCI ...

The experimental ultrasound data is always trained by measurement errors, internal and external noise. For this reason, it is always necessary to apply some signal processing operations, such as ...

When a transform is added, it appears to hang on helm.v4.Chart resources. When the function is minimally tweaked to be a transformation, it works. When registered with ...

Introduction: Near-infrared spectroscopy is now a popular method in neuromonitoring. Derived parameters like cerebral oxygenation index or Fast Fourier Transform based coherence estimates between ...
